I appreciate you going back in there to bring us this info, but I just can't take it as gospel without some sort of photographic evidence.
Here is the image we used to compare the Disk to the prop

In this image I superimposed the 1:1 scale disk outline over a 1:1 scale version of the blaster, then I reduced it to fit the post

I just find it hard to believe that there are 2 items that are this similar.
When you also consider that other parts of the turntable have been used for props it just makes more sense that this is a Thorens Disk and not some other random item that looks identical to a Thornens Disk.
It may be possible that the prop department made a hero prop with a real disk and then stunt props with thicker replicated disks

How are we "confirming" that it's not a Thorens disk?
Because if it's not It would be extremely coincidental that there are 2 items that have almost identical dimensions.
The lip width, bolt spacing indentation in the center, it all seems to line up with Thorens disk.
I've very recently seen very up close photos of this prop from the archives in a private collection. There's no indention, and it's one piece part.. so not a thorens on a spacer or anything. Believe me, I wanted it to be.
Am I imagining things or is the disk thin in the areas indicated by the white dots. The bottom area between the dots looks thicker as if it is on top of something.

I was looking at all of my pictures and I noticed that in the picture of the original Thorens Parts the disk looks really thick -

Now I am starting to think that the replacement disk was not exactly like the original.
It's a bearing cap so if they made the replacement part from thin stamped metal all they would have to do is provided shorter bolts to make it work
Originally we thought the thin disk was installed with the depression touching the blaster and the rim was elevated up off of the bracket but now I am thinking it could have been a thick original disk installed just like the original disk it the above picture.

Also on a different note, Master Replicas, who probably had really good reference material, also chose to put one distributor ring on Luke's ESB blaster. Though they also put the motor could plate on, and that's not in our photos
The Disk in the lower part of the image Boba just posted, seems to me to be the correct thickness to match the "Original". I do think I see a dropped shadow which makes it look thicker. I will be putting a 0.5mm washer under the disc to replicate that raised effect, as I am going for a heavily weathered but idealized version.

..........Could the not-Thornes disk have been from another turntable that had similar dimensions, or did they manufacture a disk of similar dimensions so the screws they used didn't have to be cut down? Just a thought, since they had a piece of aluminum cylinder chucked up in the lathe.
The gun on display is the same as in that picture. Weathering matches up, no alterations. Not a thorens disc. There is no mistake. The inner circle in that diagram wasnt even there, there was no inner dent. Its just a circle with 3 screw holes. I don't want to debate it anymore, I've seen it in the flesh, my last visit was specifically for checking this point.
I'm not building this gun, and wasn't interested before so I'm gonna back off. Hopefully this exhibition goes to the US.
That's that as far as I am concerned. Why did they do 3 holes like the Thoren's disc? Who knows . . .
Boba I would be in for a flat disc of the proper size if you want to do one.
