I picked up a nice Original 65 yesterday but it is not cocking.
I've not had a giss rifle apart yet, so I'm wondering whether this is a trigger adjustment problem, a seal problem, or something else?
My bet is a perished seal set as it looks like it's never been opened and it was made in 1972.

I've also got a 75 here that needs resealed as well, so I better get on this learning curve sooner rather than later!!

On a side note, I'm looking for a diana rear sight and a butt pad please.
