As I read this Thread, again I am amazed at all the hard work you guys are putting into this search. Chris, and everyone else, great work.
I wish I could do more, maybe if the parts were donated from various members I could paint, weather and assemble an Obi-Wan Saber for this guy or something? Send it to Chris and he could sent it to the guy (after accurate emitters are produced).
This Saber is what pulled me into the RPF and replica Sabers in the first place, and an all real-parts ANH Obi Saber is all I ever wanted from this hobby. An exact replica would be okay, but if anyone is able to secure the real part (in a small bulk order) please do not hesitate to contact me and count me if for purchasing one- and we can keep it confidential if you wish, just drop me a note. I won't be happy, truly happy, until EVENTUALLY I get one of these.

Time for Prop Runner to re-enter the fray... 
This time I corrected all the proportion and scale discrepancies between the new photos and my previous 3D CAD model. Still, lens distortion and forced CAD perspective might account for some small errors in the model:
I added a sunken lip (slight counterbore) before I begin the chamfer (taper) - this accounts for what we earlier assumed was a "pushed in" ring. I also softend the chamfer's lower edge with a fillet radius, as best I could interpret from Chris' new photos:
Each of the 16 radial holes has now also received a small edge chamfer, as is evident in the photos Chris posted of the new pipe:
As is clearly observed in the screen-used emitter above, but less directly in the restored Derwent balance pipe beside it due to the thick coat of silver paint, you can still make out an outline of the thin-walled inner pipe along the inside diameter of the emitter/balance pipe. In the first balance pipe Chris brought to everybody's attention, we assumed that the outline was a result of the protruding inner lip, but since this version of the pipe doesn't have an inner lip, it's back to my previous theory. Have I lost anyone yet? In my previous theory, I made an informed speculation that the balance pipe assembly is composed of three parts:
And one final comparison - notice the clearly defined edge chamfers on the 16 radial holes and the hairline-gap between the pipe flange and the Ring of Holes. That dark boundary line suggests either some sort of sealant material or a slight step between the flange and the ring in one direction or the other:
Chris, can you ask your source what's going on in that transition? I doubt he can separate the parts without damaging them, but perhaps one of the manuals in his possession will clarify this point. Also, could you please ask what happened to the 8 holes on the inside pipe that I copied over into my model from the cutaway diagram of the interconnector assembly? They don't appear on the Mk 8 balance pipes, despite their inclusion in the Mk 5 diagram. I suppose between the Mk 5 and Mk 8 they could have been omitted from the pipe design (or left out during a mod) - would be curious to know why if that's the case. I'd be more than happy to delete them if they no longer belong.
And I'd be grateful if our gracious benefactor could look at my design and tell you if there are any inaccuracies or interpretive errors, or at the very least correct my rough dimensions, labeled A through J:
(Notes: Drawing is obviously not to scale; all dimensions are in mm)
Oh, and if the Derwent engine he's helping restore needs any replacement parts machined from steel blanks or rods, I'd be happy to save the project some money by donating my time in generating 3D models and/or 2D CAD drawings as a return favor for all his generous and unprecedented help.

So, there are only seven emitters per engine, and not 14 as we thought earlier. That makes it harder to justify the acquisition of one.
I thought the outer diameters for step 1 and 2 would have been fractions of a millimeter below 30 and 40 mm respectively. Nice, even metric dimensions.

Looks like my model is only off by 2 mm on the flange diameter, inner pipe ID, and max height - pretty damn close.
Then again, the numbers Chris received are for the incorrect balance pipe. Hopefully with the correct dimensions of the new one (minus the layer of paint), I can tweak my model one final time. I'll be happy to offer 1:1 scale detail drawings in PDF (Acrobat) format of each component of the balance pipe subassembly, if they can be separated, or barring that, overall dimensions like those above, plus cross-section views and the correct chamfer and hole callouts.
Good stuff - I'm loving this proccess of discovery...
Cheers to Chris and his source for providing the photos. Andres - if you DO have a real opportunity to buy the correct balance pipe, my digital calipers are waiting. - Gabe
P.S. Thanks x 1,000 to Whackychimp for his continuing bandwidth generosity.

Nice Drawing Prop Runner..

This thread just keeps getting better and better.
Thanks to all you guys who are playing Ace Detective, especially Chris.
gabe, your drawings look great, I can't wait for a final accurate blueprint of this piece.
I know many of you want an exact copy of the piece, as do I, but someone needs to be thinking about making a version that will fit onto available Obi sabers. A bunch of glue and filler, while probably accurate in the extreme, will look pretty messy on a collector's piece. N'est pas?

Polloxius--the last word posted on the gear was: probably not.

you guys need to stop posting this stuff for free and make like a newsletter, as many of us are loyal readers, you would already own a couple of the engines.
LOL.
scratch that, i dont have any subscription money...
keep up the awesome work.
cant wait to see these things come to fruition.
awesome, just awseome.

You know, it's kinda sad now. After all this, we've narrowed it down to like 99.99% positive identification, now I miss the thrill of the hunt.
Maybe that's what this entire hobby is all about. The thrill of being the one or part of the group that makes an earth shattering discovery. I know there's still the gear and correct make and model of transistors, but the starting from scratch can be frustrating. At least with this, we had a lead, no idea if it was right or wrong, but it was close enough to be worth a look and it panned out.
The gear, even after having looked at thousands of gear shaped doohickies, is still illusive because it can still be one of the doohickies we looked at, just not the correct model. It can still be a version of the fluting iron, or a gear from a different engine - who knows.
Anyone else feel the same, sad to see this come to an end?

Exactly the same, in fact.

edit: looks like the Nene 10 is a bust. I received these photos from my contact:

KD, looks like a good emitter for a custom Saber though

i was thinking the same.
