Diana aperture sight eye cup

[slow_runner]

Following on from my Diana 35 thread.
It came to me missing the rear sight but wearing an early aperture sight.
It functions well enough but is missing the eye cup.
Bicycle tyre tubes can be made into functional items but I would rather not embark on that solution just yet
It requires something in the order of 40mm diameter.
Any suggestions where I might find a close replica of the original item?

This is what the original eyecup looked like (pic by Mike D).

Big Iris- big cup. Most are around 1" now. Does the sight pre-date the gun?

Thank you for that reference link Garvin. I have since come upon a more direct perspective courtesy of Mike Driskill in this image

It is large alright Drew. I believe it is from the 50s M series(?)
I am only going on the little that I know, maybe someone with better knowledge will confirm or clarify that for us.

I think you are right, Slowrunner. I have seen the type on earlier 50's and 35's from the early 60's. You may struggle to get an eye cup to fit. To be honest, I find the standard Diana and FWB diopters work fine without. Good light at the target is obviously helpful.
I'm wondering if a smaller iris can be retrofitted to your diopter if you can find one at a good price.

IMHO, the plastic eye cups are/were a bit of a gimmick. I'm not sure they actually improve anyone's shooting, at least not by much.

For me, the difference in sight picture with/ without is marginal. I can live without quite happily.

Interesting juxtaposition of the 1950s Falke and Diana flagship match/sporters in that pic, Trev.

Reminds me of a comparison I did years ago of the early 1950s Falke and Diana list prices - amazing but true that the Dianas actually cost more, despite the diopters and rearsights being pressed steel, whereas the Falke ones were painstakingly machined.

At the time, I thought (wrongly, I think now) that it might have been a price war which fatally weakened the fledgling Falke company.

Drew, it works well enough for me too although if I can complete it I will. I don't have much hope of that eventuating though.
I buy lottery tickets too.
