Hi all, I have an old Diana air rifle not sure the model maybe a 16 or 20 but dont really know, can anyone give me a clue and possibly value.

its 82cm in length, brown wood stock and everything else is metal, .177, I think we have owned it since the early 70's but don't know if we had it new or not.

Also does anyone know if you can get spares for them and a breakdown diagram as interested to maybe diassemble and clean it up.

Sadly it has a small crack on the top but dont think it would affect its use. The barrel is smooth not sure if thats by manufacture or just worn out and most bluing has gone.

Anyway here are several images of it. https://www.dropbox.com/sh/z0jcz210u...j6d0UA9Ga?dl=0

Appreciate any info

Cheers

Martin
