this week is sort of an anniversary, two years ago this weekend we were at an antique show and I painfully walked away from a light 12 Parker 28" O hammer gun at a very reasonable price because I knew the barrels had been honed but had no way of knowing how much.
That is when I started posting here, originally asking questions about wall thickness gauges. Since then I have passed on a couple Birmingham guns and almost on another Parker because of thesame question.
Now I am ready
here is the latest tool kit that will ride in the truck on the off chance history repeats itself.
I found a beat up wood box labled for a depth gauge, it had no finish, a boken latch and sprung hinges, but the pigeon crap was free. I cleaned it up, reglued the finger joints, replaced the hardware, varnished it and lined the inside bottom with felt left over from restoring a Machinist's chest restoration, added some brackets and a small box for storage,
so here is the end result - it has a walll thickness and a bore gauge, the box insert will hold a tape measure, a scale, a magnafying glass and I'll toss in some snap caps. all that remains is to find room for a small digital caliper, and add some elastic straps to hold some papers with bore and choke specs in the inside of the lid.
if only I could memorize the serialzation book
