Are you asking opinions regarding what constitutes a Parker "Live Bird" gun?

or what is a Parker Bros. No. 7 AAH? Early guns were marked as "Pigeon Gun" on the top barrel rib. The first AAH Pigeon Gun SN 79964 was delivered to Capt. Du Bray in 1894 and at that time, it was Parkers highest grade selling for $400 = about $12,000 today.
