OK, time for more info.
Number one mystery seems to be this ring of holes and how it actually works to transform into how it looks on the lightsaber prop.
Short answer: not sure. It's still in the hands of my source and he is as concerned about it as we all are - a Star Wars fan and obsessive eye for detail? Did I luck out or what? Truly this guy is a HUGE help.
He's not entirely certain of his original assessment that I reported and is looking into the ring of holes more. He is going to check with another guy more familiar with the engine. He's in the right place to figure this out so I'm content in waiting while he does. More answers will come about how this thing fits with other parts too.
He recommends holding off on the scrap MK8 for now - until he figures out the specifics.
He's all for us going after the scrap engine, but wants to guide us properly and be more certain about things.
Some pause between correspondance with the scrapyard might be good anyway, don't want to seem too eager.
I was very honest with him that there was some apprehension about scrapping this engine for parts among us SW prop fans. As I told him - A Graflex camera without a flash is one thing, a Meteor grounded due to lack of parts is quite another.
I mentioned the engine found was a MK8 in a scrapyard and was previously used as a de-icer.
He says-----------------------------------------------
I'd heard about those de-icers. It's tough to say; these things can look great and be terminally cracked, or can look knackered and be salvageable (at least in part). Only an engineer could tell you whether the engine in question has potentially airworthy parts. On balance though, I would say go for it. You can always donate the parts you don't want to one of my contacts, that way you're helping SW fans and the "warbird" movement. And saving on shipping costsÂ
--------------------------------------------------------
I think it's only right if we get the engine to make sure the parts we don't need go to people who can use them. Whether we charge for them or not can be decided later. The engine is very expensive and offsetting the cost a little would be nice. I did not tell him how much it was. I should ask his opinion about the price.
THE GEAR ---
I sent him a pic of the prop gear (with general dimensions) and told him it may not be a true "gear" but something else inside the engine, possibly cut down.
Any more ideas regarding the gear?
Are we certain it's metal? (he asked)
OTHER PARTS ---
Besides the emitter, gear and IG-88 head (more on that later) is there anything else you might suspect is in/on the Derwent?
Before all this I found the front and rear air intakes (Luke's T-16 and Lars' Speeder) and the interior and exterior of the combustion chambers (Mos Eisley Cantina distillery), now it's time to go more in depth. I will be going over the engine in much more detail and my contact is willing to help.
I didn't really see anything on any blasters to look for.
Lightsabers are covered (besides the "gear")
Nothing much on R2 either.
I'll check for other ANH droid parts (and more IG-88 pieces).
I suspect landspeeder parts, but is anyone going to build a landspeeder? (I will look anyway)
Spellbinder - Thanks for the info regarding the serial numbers. That makes sense.
That's all for now.
BTW - If you guys wonder if you're dreaming, you should know I feel like I need to remind myself this is really happening too. My contact has been so incredibly helpful and this is going very smoothly. He's given me lengthy, informative and enthusiastic replies and then he asks and suggests how he can help more.

Thanks for the update, Chris.
I hope some of my artwork and follow-up questions will make themselves useful in your ongoing communications. Please let me know if you'd like to see anything visualized using CAD to better express your verbal/written queries.

WOOHOO....
thats great news on the discovery guys
Well done to everyone who brought this about :cheers
Its nice to see threads like this on the RPF again.
I can't believe so many pieces have been identified this year.
thanks for posting the pics Chris, great to finally see the real part after all these years.

Very cool... It's interesting that the ROTS Obi saber, despite all it's differences, has that little lip on the ring of holes too. Makes you wonder if they had more reference material than these same B&W photos we've been looking at for years. Hmmmm.....

I wonder if the real emitter part was machined with a larger bevel on the flange than the found part, because it does look so in the Chronicles pic. I.e. the same part with a slight variation from manufacturing. I guess we could take a better guess once we have seen more of these.

Bevels (or chamfers, as we engineers like to call them) are almost always added for the purpose of breaking sharp edges that would otherwise make alignment or insertion between parts more difficult or present a safety hazard. You'll notice that most machine screws, nuts, and glass tabletops have chamfers for this reason. Corner chamfers are added to reduce the shear stress at a sharp 90 degree transition. For that reason, corner chamfers are typically larger than edge chamfers. Also, because sharp corners require sharp bits, and metals like steel and titanium eat up tool bits at a faster rate than aluminum, brass, or copper, corner chamfers extend the tooling life of the bits. Finally, both edge and corner chamfers allow easier extraction of cast and injection molded parts from a mold or dye and promote better molten material flow around sharp features.
Variability on the lengths and angles of a chamfer can be caused by a worn chamfer bit, or due to the fact that a part was machined manually rather than using CNC. Since chamfers are not geometrically toleranced features like diameters, concentricity, thickness, flatness, straightness, length, etc., some variability would not affect the the performance of a part or cause it to fail quality inspection. Given that the Dewert engines predate CNC machining, I'd say some chamfer variability should be expected.

Any chance that some of the parts of R5-D4 came from the Derwent?
sorry for the pic hijack.

I think we should compile a list of props and prop parts we know are still unidentified and look like they could conceivably come from an engine. Something like the Obi gear could definitely come from an engine, something like Han's ESB Hoth scanner, probably not so much.
Just an idea, maybe worth pursuing, maybe not.

In my opinion, the chronicles OWK picture was cropped and doesn't represent a good outline of the saber.

Im still amzed, the flash hider is one thing, where it is pretty easily identified as coming from a gun.
This emitter, amazes me that it was tracked down. If you think of the endless possibilities that have been offered as its origin, it is mind boggling that it was able to be traced.
Outstanding.

Franz, There are versions that are not cropped, in which you can see the table the saber is resting on. It is such a version which circulates here and is normally referred to as the 'Chronicles' pic.
The interpretation of a bevel on the flange is not from outline shape anyway.

This thread has gotten so big that people aren't reading the whole thing, and information is getting missed.
I think we need to start collecting major points, i.e. issues to address, parts to look for, ways to ID the right engine, possible variations, etc. in one place so that it can be reviewed quickly. Maybe the first post of this thread? Or a new thread?
Regarding how many emitters there are, and which one we're looking for, this is again the quote from the engineer I reached (who has not responded to my recent emails unfortunately):
"the picture you have is of a Derwent mk 8 or 9 but most likely a mk 9 interconnect. There are a few different sizes of inner bore diameter depending on your mod status and there is also two per combustion chamber with different flange diameters each. The picture you have looks like the left hand side as you look at the balance pipe."
