Raimey, Here are the pix you requested. (If there is anything else you want to see ask ASAP before I put it back in the safe.)
The brld actions I have/had were serial number marked with a B prefix and in the mid 300 and low 400 range.
These pix pretty much show all of the marks of the original metalwork.
Some of the barrels were marked differently but I do not have images of them. The bores are polished but unfinished without any chambering, tight chokes and minute traces on the barrel marks showing as tiny dimples inside. These dimples will clean-up with finish honing.
