Just been given a really old 50 that's in a box of bits with a cracked pistol grip, though I'm assured everything is there. I had an early ball bearing trigger years ago but this looks much older. I'm struggling to see any date stamp in the usual places, but it has a lot of chequing on the grip and foregrip and an adjustable foresight, of which I've never seen. What year were these made from? I'm not sure where to start with it but like to get it firing again. I'm struggling to upload pics unless it's a sales thread.
I'm thinking of sorting the crack first and take it from there. The scope rail is in two section, was this a target model to take a diopter?
