Unstruck barrel wieght

[winplumber]

Were some 12 ga hammerless top levers barrels also bored to around .754 before 1892 When in March of 1892 the standard became 0.729 / TPS page 517 or is this just the T latch guns? Whats the most you have seen struck from barrels that was factory ?

Factory 12 gauge barrels, hammer and hammerless, were on the "close to .750" side before 1894. I don't know how much the factory took out on a cleanup, but the order book repair order is the only proof that such was done. Without the order book entry, there is no proof that anything was done at the factory.
