A bit of metal could then be locktited in and touched with blue if you wanted.
The Senior had the barrel pivot screw drilled out and the remaining thread picked out (very impressive) + the 2 trigger guard pins knocked out.
I stripped the gun and gave it a bit of lubriction, planning to strip the gun again and try to clean it up a bit. It would not cock very often. I tried swapping the sear and the trigger spring and even 2 barrels and full linkage but it was still the same. I think the small link is worn so it is probably worn on one of the other pistols I tried. On closer inspection, the long link had been fitted the wrong way round. Once I put it the right way round and the right way up, the gun was cocking every time. I still think the cocking fulcrum lump at the front of the cylinder could do with building up a tiny bit with weld though.
I need to sort out new link pins as one was a bit of nail/pin. Also need to get a barrel pivot screw.
Hopefully I will get this cleaned up bit and the plan is to go over it with a bit of Plum Brown and see how it looks.
