Well no, I don't necessarily think it has a lot of intrinsic value. Someone however did ask a question about it. "If" I asked about a Crescent I would appreciate an attempt to answer the question asked, & not "Well it's not A Purdey, so not Worth Discussing". As to the stamp, yes it is quite possible to make a mirrop image stamp, all I was saying was they didn't just pick up a letter J from an alphabet set & stamp it backwards as this don't work that way. It is at a location where the bore size should be stamped which should consist of two mumerals & not a letter & a numeral, forward or backwards. If that was not intended as an 11 then they totally omitted the gauge marking, as is not present elsewhere. This gun was proofed prior to the chamber markings.
