Bore diameter for a circa 1885 10gauge TLH

[Craig Larter]

From my reading of the Parker Story a circa 1885 10gauge top lever hammer gun should have a bore diameter of about .805 which is above the later standard of .775. I would appreciate any feed back on measurements from 10's in this era. Thanks Craig

My 2 frame 1889 hammerless bore was .802 if that helps, choked .025 in both

The question of 10, 11, or 12 gauge Lifters will always be in question according to Richard Hoover…

Again, according to TPS the answer lies in the production records.
