I am very fond of some of the classic Dianas.
I have a nice Diana 58 third model that needs a bit of refinnishing (looks like plastic wood) was added to part of butt area.
Interesting gun since it is a miliatry trainer, 80 years old about dating to 1930s. Im always interested in acquiring a second model.
Other variants I have in my collection include 4 Diana 50 underlever guns. I have several of the first model with the solid steel cocking lever-really overbuilt but I havent found much time for shooting-too busy collecting.
I really like Dianas and BSF guns, I have a BSF 55 in nice shape, a spotless BSF S70 and a nice underlever model with the large peep sight.
