Mike;
The only pre 1887 English guns I have are all cylinder bore. 1 muzzle loader, 1 pin fire & 1 side lever center fire. None of these thus have either marking, only a single gauge mark. All three of the sources I have for proof marks (Wirnsberger, Englehardt & Kennet), though seem to agree the word choke replaced the Not for Ball in 1887, along with the other changes mentioned. The gun pictured here has no indication of a "RE-Proof" & I assume neither do yours. It seems to become quite obvious that for at least some portion of time "Choke" was added to the old markings with no other change. Do you have any other means of dating your guns other than the proof mark period? Thanks much for your input.
