Agree with all of the above on the proofs except cylinder for the R barrel. Absence of the "choke" mark COULD mean cylinder, or it could mean it has some choke--but not a lot. Anything less than .008 was not required to be marked "choke". However, I found that in Engelhardt under the rules of 1904. This gun passed proof under the 1896 rule, and I can't confirm that the same rule for the "choke" mark was in force then. So don't be surprised if you find a little choke--but DO be surprised if you find a lot!
