I didn't expect it to be that old with the 2 3/4" chambers. it did not have 2 3/4" chambers when it was first proofed - the 12 over C in the diamond would have been marked 12 over LC, indicating long chamber.

Lot's more fun MAXm confirms 1896-1904 Birmingham date code 'T B' - 1968 London Proof 2017 Bore 13/1 = .719" - .728", then .729", then 18.7 mm = .736" Do you think that's a "T" rather than an "M?" Are we're thinking three trips to the proof house? You're the 2nd one to mention that.

The problem is that some early proof marks are lost or marked over with later re-proof Lloyd's gun was proved 3 times, and the Birmingham date code is pretty clearly a 'T' https://sites.google.com/a/damascusknowledge.com/www/home
