Having mentioned that 300 Gloster Meteor Fighter Jets were build under license by Fokker here in the Netherlands, I'd now like to present to you the motherload of Mk8 engines of which at least 2 have been confirmed to have had the Mk9 upgrade . . . unfortunately for us, Obi-Wan lightsaber builders, these jet-engines are being kept in a depot belonging to the Nationaal Militair Museum in Soest. I doubt they would become available for a collector any time soon ... nevertheless I'd like to share the pictures I found online with you all :

From the thread made earlier by schrodinger555 'Some Thoughts on the Obi ANH Transistor Washers' :
'So given this exploration the dimensions we are looking for are as follows:
13.6 mm OD
8.23 mm ID
2 mm thick
10.6 mm recess diameter
.535 OD
.324 or 5/16 ID
.078 thick
.416 recess diameter'
I now present :
From a seller which was already in the picture, yet now has the more accurate washers size-wise available in his ebay-shop.
Here are some specs from the seller's auction :
... still the outer diameter is to large and some have an inner diameter that needs adjusting to accommodate our transistors.
These type of washers apparently date from 1971 :
Though the ones I found may be of a later fabrication date and have been manufactured by :
Another picture from the auction :
Since these washers are still a bit to large thus in need to be altered and being sold from Dallas, Texas I reached out to scottjua who was more than willing to investigate ... 'They're local to me. I sent them a message to see if I can pick them up' ... so he made contact with the seller and the next day went out to see them in person, bringing along an ME transistor to make certain those washers would fit properly.
The following day I received this message :
Scottjua even went to work on a bunch of them and resized to the specs as mentioned above ... here are those pictures in close-up:
So eventhough these newly found washers still need some adjustments to fit our transistors properly, at least the thickness of 0.078 in/ 1.98 mm is now more accurate to the calculations made by schrodinger555.
Now if any of you are interested in a set of these washers ... please contact scottjua for more info ... or perhaps even better ... wait until he joins us here with a link to an interest thread in the junkyard

onderon found a bunch of these like 3 weeks ago. Same dimensions. He posted in schrodinger555 thread. No one said anything but they are same and nos. Just sayin.

They already have the bevel but it looks like the degree is off.
Edit. It does look like a bevel step bevel in that last pic.

Yeah what I mentioned are better OD but not 2mm thick. (0.057 inches = 1.44mm thick). I didn't order it, because the shipping to Europe is 255 USD. Of course I've seen these NAS1587-5C too, it is the same seller, but since it is much wider than what schrodinger555 measured in his thread, I skipped.
I should have said "pretty much the same" but still need to be machined.
Until we find something that doesn't need to be machined it's irrelevant. I have a bunch of vintage washers. Inside diameter perfect and recess looks great but outside diameter needs shaving. I've looked at hundreds of these washers. Not one hits every spec. I would go as far to say that its possible that the prop makers machined the washers they had. Or we just have crapy pics to scale from and are getting it wrong.
Either way this is a hard item to pin down. One of the hardest we have tackled. So in my opinion. Using the scaling that we are going with for now, and the washers we have found. The ones that take the least machining are the best to look at. And so far You, schrodinger555 and onderon have found the best we have seen. And are all viable options.

There are also these
According to this they are from 1975
But still too wide, maybe not even thick enough if our measurements are right. Looking at this picture it might not even need machining. Who knows.

I did basically the same thing Scott is a while ago, I bought a bunch of them and machined them down and offered them on the forum. It is a good solution and matches the dimensions I had come up with, but the issue is that they still needed modifying. I've looked from time to time but haven't found anything I liked better. I found some helicopter beveled washers that look quite good but are pretty thick and a bit too wide in the OD.
So I think the crux of the matter is we don't have any vintage pieces that exactly match what we see in the Chronicles shot, and to make things more interesting the Death Star shot appears to have a wider and different washer as compared with the Chronicles photos. This makes sense to me as the common consensus (I believe) is that the saber was rebuilt slightly for the Chronicles photos.
In my thread I based the dimensions all on the Chronicles photos I had access to, including the sideways shot to get an approximate height. The proper Anita IC's may have a different height than what I found on there. Maybe Scott can measure his and see whether my height is accurate to the Anita IC?

When were the chronicle photos taken?
