Found! Obi-Wan Kenobi ANH Lightsaber Emitter

[lonepigeon]

PR - Forgot about that old post. This thread has gotten so big we're duplicating info a lot.

For the third or fourth time, the Dehavilland Comet used Derwent Mk.8's. The part pics I've posted came from a Derwent off a Comet.

Check my post earlier re: the Cantina.
The John Knoll book has a nice big pic which shows 6 combustion chambers and 8 flame tubes behind the bar. That's still less than one Derwent's worth.

Those aren't Derwent flame tubes in the Falcon. Derwent flame tubes don't have holes in the top like that. Those tubes are why I said we have parts from at least 3 planes spotted so far (Derwent parts, Viscount parts, plus whatever those came off of)
Only one gun port was built.

The "Looks like it could be from the Derwent" caption in the DS gun pic points at the piece I was thinking of earlier that could be the Derwent nozzle box (#11 in diagram).

There was only one gunport constructed for ANH. They shot Luke and Han separately for the dogfight and cheated the over the shoulder shots.

The Comet? Really? I did some web searching, but did not find any info about the Comet having been fitted with Derwents. Only the De Havilland Ghost 50 for earlier models and the RR Avon for later models.

A little more web search reveals also:
The Derwent mk 5 was used in the Canadian Avro Jetliner and the Soviet (.) Jak-23. ("Yak-23")
The mk 9 was used in the Italian experimental aircraft Aerfer Sagittario 2.

A derwent was also strapped into a Vampire for some speed record thing. It's possible that a few Vampires (or Vampyre, not sure of the spelling) were outfitted this way. One could have ended up in the hands of LFL.

As for the nozzle box, it likes it could have very well been the basis for the probe droid head.

TO THE SEARCHERS:

Just to reiterate Chris's comment about coordinating efforts, know this: Chris is a standup and ethical guy and will do the right thing when you tell him who you're contacting. When he found out that someone (his main guy I think) had been in touch with my contact he had him pull back. If you send him a genuinely new contact he won't BS you.

So it's in your best interests to run your ideas by him. It will stop you wasting time and possibly causing problems for others, and it won't hurt your search at all, because your new contacts will remain yours.

Also keep in mind that shooting may have wrapped on a set like the Cantina, they would strike the set, and then re-use the hardware in another set. This is described in Knoll's book and happened frequently. It was one of the ways they saved a lot of money.

DOH. :$ Roger, Roger - forgot about the Comet comment. And yes, the thread HAS become a very unweildly (pardon the saber pun), but it's better to repeat info than to miss it, n'est pas?

The John Knoll book has a nice big pic which shows 6 combustion chambers and 8 flame tubes behind the bar. That's still less than one Derwent's worth.

Thanks for the clarification. I just looked, and the Chronicles also has one photo on page 74 where at least 4-6 can be seen.

Those aren't Derwent flame tubes in the Falcon. Derwent flame tubes don't have holes in the top like that. Those tubes are why I said we have parts from at least 3 planes spotted so far (Derwent parts, Viscount parts, plus whatever those came off of)

Thanks, Chris. For the lazy, here's what a Viscount looks like:

So to be clear, which non-Derwent parts came from the Viscount and the Silver Star? Could you post an updated verified list? (plane/engine & prop/set piece)

The "Looks like it could be from the Derwent" caption in the DS gun pic points at the piece I was thinking of earlier that could be the Derwent nozzle box (#11 in diagram).

Can somepone post clearer pics of the DS cannon? It would be helpful to get confirmation.

Regarding what Chris said about duplicity and dishonesty in communication with sources, I strongly agree, and have often posted those exact admonitions in this thread. Honesty is ALWAYS the best policy - even if doing so risks losing a source who decides not to cooperate. I employed full transparency, courtesy, discretion, and integrity in my search for a Han Solo flash hider (the German MG81 aircraft machine-gun booster-flash hider) in good condition, and it's finally paid off. See pics of the part I've got coming in a couple of weeks:

In my case, too, this veteran licensed machine-gun collector and shooter turned out to be a big Star Wars fan. Since our initial contact, I've been educating him on all the German, British, and US weaponry and greeblies that were employed in the Trilogy, and he's eating it up like a kid in a candy store.

Alright, my bad on the DeHavilland Comet. Turns out I read an e-mail wrong from my source.
Rolls Royce Heritage helped him track down the origins of other engines including an RR Ghost which the museum had. He did not mean that the Comet had Derwents.
So strike the Comet. (I'll ammend my previous post to avoid confusion).
PR - Silver Star? not used as far as I know. I was thinking you said it had a Derwent in your old post. Again more confusion from giant thread.

Here's a bunch more info from my source (who actually saw this thread and commented to me):

"...No *production" military or civil jet did [have Derwents] other than the Meteor. The Vampire thing is a red herring, as even if one aircraft, or even half a dozen, had been fitted with Derwents, the chances of any of these surviving is virtually nil. If they did, they'd be important museum exhibits.
So it's Meteors and ex de-icing engines only as far as I know. But, you also have Belgian, Dutch, Argentine, and Egyptian sources to research. I have few contacts in those countries, but would be willing to make some if people can help out by researching museums and private collections in those countries. As we know, the only flyers are here and in Oz, but there must be aeronautical jumble type collectors out there."

"Oh, there might be one other long shot source for Derwent parts; the former Soviet Union. The UK sent unknown numbers to the Russians to be copied, although no production Russian types used the Derwent copy, but rather the more modern engine made available to them; the Nene. This was the powerplant for the MiG-15. That decision really came back to bite us (and the US more so) in the arse in Korea."

"As to types using the Derwent, the only one I'm aware of is the Gloster Meteor Mk.4, the FR.5 (thse two used Derwent 5), and more usefully the Mk.8, the T.7, FR.9, NF.11, NF.12, U.15-16, U.21 (drones), and TT.20 variants. As I think you knew, the Derwent was developed into the Nene with relatively little modification, which explains it's apparently limited use. Other than that, the Derwent was a first generation design and all other airframes on the drawing board that might have used it or a variant were really in need of one of the new axial-flow turbojets. So it must have been a Meteor, and considering the time-frame, most likely one of the target tug or drone variants. Mind you, a 1976 scrapyard could have yielded any of them. I could ID it from a set/production photo if one were found."

So it appears that a Meteor MIGHT have been the full plane they had. We know they had parts from at least 2 Derwent Mk8 or 9's.
The Viscount was the source of R2's holoemitters (overhead reading lights). As far as I know those are the only parts ID'ed from the Viscount so far.
3rd possible plane is the unidentified source of the Falcon gun.

Is the Falcon gun def. from a real plane??

[b26354]

The viscounts had a Rolls Royce dart turboprop with 2 compressor fans and 7 combustion chambers (very similar design to a derwent but with a propellor stuck on the front). Is it possible the chambers from a viscount engine were used for the Falcon guns? Is it possible the dart had balance pipes like the derwent?

Here you go:

The combustion chambers seem much smaller on the Dart engine. Everything about it appears smaller than the Derwent.

Here's the link to the large image:

[Killdozer]

I did some research on the dart today and I'm now pretty sure that the back half of the propeller spinner was used both on the Death Star Gun (in front of the impeller) and as a little table in the back of Ben's hut. Anyone have the wide angle set shot of the hut by chance?

Anyway, this research led to looking at a whole lot of pics, whic led to looking at a whole lot of other pics.

I think this thread is about to get a LOT bigger.

[DCB]

Seeing as we appeared to strike out with the Derwent, could the Dart be a possible source of the Obi-Wan gear? Or perhaps the engine of the mystery 3rd aircraft?

 

[TheRealMcFly]

Welp, theres the gear.

Theres not going to be anything left to do here on the forum if things keep going at this rate.

What?

Except build super accurate props.

 

[Macklin]

Holy crap.

 

[JHVanOphem]

Could it really be?

 

[Mr_Creepy]

KD--email sent with Ben's Hut pic. Great find on the gear--so how extremely rare are these? :lol

 

[Serafino]

:eek wow.

 

[franz bolo]

If that's all Serafino has to say, then this MUST BE BIG..

[lonepigeon]

I think we need a new gear thread.

Nice find. I was just starting to look at gun parts for that piece too. There was background blaster built for ROTJ that had a similar piece on it which got me thinking in that direction.

The Dart combustion chambers are very different, but they look familiar.
See here for pics:
http://www.users.zetnet.co.uk/gas/combust.htm

KD- I agree with you on the back half of the propeller spinner being on the DS guns and in Ben's hut.

I think that Derwent nozzle boxs may have been rigged with lights and used as the Death Star tractor beam thing that Obi-Wan shuts down (top and bottom).
Could be more evidence of two Derwents used.
The impellers on the DS guns definitely look like Derwents (vs. Darts) because they also used the attached shaft.
Also the things hanging from the Death Star chasm and in the Tantive IV hallway (see #6 in John Knoll book) look like engine cowlings. They look similar to the Dart's, but lack the top intake detail.
