Correct rear sight for Original 75?

[thisisdonald]

I have an Original 75 1979 that requires a rear sight, I want the correct one.. anybody help with details please?

[Drew451]

The rear sight is known as a Diopter 75. Can usually be found for around £50 ish from time to time.

Thanks Drew, oh thought that was too easy. I'm looking at the ones on druckluftwaffen and they say that they are stamped or cast with '608' on them. I'm wondering if these are the correct ones for my period rifle. It is not a T01 model

Can't seem to find that site with the diopters. I'll have a look for any stampings on mine tomorrow. The T01 era diopters do differ from the earlier model 75 ones ( fitment-wise).

Donald,

Any of the Diana/Original diopter sights will fit on the Mod. 75.

My Mod 75 has the 75 sight (straight 'wings' from base to the vertical body), and my Mod. 66 has the 60 sight (curved 'wings')

The 75 tends to be smooth finished, while the 60 has a rougher, almost parkerized finish.

The manual for my 75 also suggests that there was a further sight available for the Mod 75 - the Diopter 82 - please see manual here :

Thanks for that Russ... I think I'll look for one with rounded wings and a smooth finish.

Just Googled diopter 82 and saw one for the first time. Quite a departure from the other diana sights. No large fixing wheel, its more like some Anschutz sights of the time.

What an treasure trove. My diopter 75 is stamped 2104. I'm sure I saw at least one stamped the same, amongst those on that fine site.

Hello to All,

There is a nice photo about half-way down showing the 60 & 75 diopter sights :

The modern Centra Spy sight looks to be similar-ish

In what must rank as one of the strangest moves ever by an airgun maker, the Diopter 75 T01 will not fit earlier Diana guns, including the “pre-T01” model 75 rifle. It’s mounting rails are slightly narrower, in addition being flat on the bottom when viewed from the front, instead of having drooped “wings” as described above.

The Diopter 60 or first-version Diopter 75 will fit your rifle. The latter would have been the OEM fitment.

The Diopter 60 was the OEM sight for the models 60, 65, and 66 break-barrel match rifles (though very late examples of the model 60, which actually out-lived it successors and stayed in the catalog until 1983, will have the Diopter 75). The Diopter 60 was made for many years and will be seen in a glossy gray-black, matte black, or matte dark green finish. It is more heavily constructed than the 75 sights, and more rounded in appearance. The underside has the number “608” and a small circular logo with the letters “SRM.”

The Diopter 75 is lighter and more angular in appearance. it will have the number “2104” and the letters “DRM” inside a small diamond-shaped logo underneath.

The Diopter 75 T01 has “T01” embossed on the top, with again “2104” underneath, and again the letters “DRM,” but larger and not enclosed in a logo.

There may well be other variations of these, I’ve just described the ones I have on hand.

The Diopter 82 was made by the Swiss firm Elite, and is a very high-quality and rare item. I believe it will fit any model 75 but have not tried it out myself.

Any vintage Anschutz sight will also fit the Diana rails. If you can live with a non-original diopter they are very precise and generally easier to find. Many an original owner used these on their model 75’s in competition, which I’ve used to justify putting them on my guns!
