stamped 32-20 CTG on 4 inch barrel, checkered square butt diamond walnut grips..penciled SN# to match the 133591 on grip frame, barrel, cylinder and ejector. Strong case colors on hammer and trigger..both stamped with the patent info. The revolver locks up tight, has a very good bore and about 80% finish showing wear from holstering. Can the date be pinned down...I know the last were from 1940. One other observation..these Model 1905 32-20 revolvers seem to book awfully high in the Blue Book. At 50% this revolver would sell for almost $500..is this a mistake on the books part? Any feed back is welcome...and thanks.
