Another excellent set of pics from Mike D, who says:
I have to say the model 50 is a great favorite of mine. IMHO it is vastly underrated as a collectible in the US...just has never had the cachet of the BSF 54 or Falke guns, for example. Sharing powerplant and trigger with the famous model 35 barrel-cocker, it was Diana's top sporter for nearly 30 years, and was a solidly made, beautifully styled, and great-shooting gun from beginning to end.
The accuracy, reliability, fine sights, and smooth trigger make it more fun to shoot than just about any other classic taploader in my estimation. The handling and balance remind me of a Mauser K98...probably not just a coincidence!
With thanks to Mike D for these pics, who says:
This gun appears to be the oldest of the four old target Dianas that I have. The stock details are subtly different from the 50/b, especially around the grip and comb nosing. And the trigger details are again different, note the use of the tiny pre-war style adjuster screws and different location of the adjuster access hole in the trigger guard (this album has a shot of the 50/b trigger for comparison).
All that's needed to turn a "50/a" into a "50/b" is the clamp-on peep disk of course! Otherwise the actions of the a, b, and M are identical.
Diana Original Model-50E.
With thanks again for these pics to John, who says:
"Here are some pics of the Original 50E, which must have been a "base" model for the UK market. This has the simple rear sight in a dovetail similar to BSA and Webley of the period, and the single element front sight. There is no rear rail as on the a,b, or M variants."
The rifle is marked "MADE IN GERMANY", as opposed to "FOREIGN" marked on earlier examples of exported Dianas.
Diana Model-50M - Peerless.
With thanks to Mike D for these superb pics. Mike says about this rifle:
The latest addition to my little airgun fold is this Match version of the Diana model 50, in this case in .22 caliber as imported by A F Stoeger of New York, under their "Peerless" name. (Stoeger apparently just didn't believe in that wimpy little Euro .177 bore, all their larger Dianas were offered in .22 only).
The 50M was the most expensive Diana air rifle throughout the 1950's, designed to compete in early 10-meter matches against guns like the Walther LG 55 series and Weihrauch HW 55. It was discontinued in the early 60's after Diana simplified their sporter line and began introducing recoilless target rifles.
I'm only making an educated guess, but the features of this gun date it to around 1956 to 58. It is in astonishly good condition, and in perfect firing order.
Diana Model-50 - Possibly the first ever.
With thanks to Peter for these pics. He says this fascinating rifle was one of two, identical, purchased by a British officer from the Rastatt factory in 1947. Its owner supposes it might be a prototype for the rifle that went on to become the first model 50.
