Ok, so 9 times out of 10 the screws on these old gun are somewhat mangled, and this really makes even a nice gun look tatty.  I am thinking about turning up a few replacements for my guns.  Can anyone tell me what the threads are? they are obviously not Metric, so I am think probably BA, BSF or even UNF  can anyone cast any light on these please.  also the piston seal screw what thread is that?

Many thanks in advance

John
