Have a look at these two my f.i.l. is giving to me.
a) what are they and how old?
b) the first one needs a mag, the second one a firing pin - first of all are they worth repairing?
c) how to go about repairing the missing firing pin, just drop them off at at a gunsmith for a going over and fix-em up?
Have another one, an old 38 revolver with a loose firing pin. It wobbles and rotates. Is this a safety hazard (for range use) or is it normal?
