I have an antique Bacon .32 rim fire pistol that Flayderman does not list. It has a 6" barrel that is half round and half octagon. There are front and rear sights on the barrel. The correct inscriptions are on the top of the octagon part of the barrel. Serial numbers are found under the barrel, on the pivot screw and under the left grip. ( number 19). I am new to this sight and am not sure how to post photos. Any help will be welcome.
