I need to source a replacement trigger blade for my Diana Model 65. It was very unfortunate that during a recent seal/spring replacement the 51 yr old plastic trigger blade broke. I need to ensure that this fine air rifle remains operable long after my stewardship expires. If anyone might steer me in the right direction to begin a search, I'd be very grateful. I've contacted some of the major parts suppliers but nothing so far. Wish me luck!
