Good day. I’m in a sad situation, after an almost 9 year hiatus, I am attempting to put my 1910 12g Field back together after 2 moves and many life changes. In unboxing my LC in its completely broken down disassembly, I am missing a 30” lower rib. That rib came off when I was attempting to re solder the upper the upper as an amateur and had too much heat. Now years later, I have a matched gun and 1 missing part. Any direction on re-fabricating or finding a lower rib?
Kindest regards and please forgive my stupidity!!
