I’ve been told some model 25-5s were returned to the factory to correct oversize cylinder throats. My 25-5 was shipped in December 1980 and has .451”-.452” throats, but don’t know if it originally left the factory that way or the cylinder was later replaced. When I disassembled it, I found the frame’s serial number on the rear face of the cylinder . . . under the extractor star.



Does anyone else out there have a similar example and do you suspect (as I do) that a stamped s/n on the cylinder indicates that such examples made a trip back to the factory for a replacement cylinder?
