Well, I'm not Ron but I'll answer anyway. My 1971 SO4 (so marked, also with Garcia markings; 5/4 pins) with hand detachable sidelocks is fully engraved and signed by "P. Bousi." My 1959 S3EELL (with two 32inch barrels, same serial nos. as receiver) has seven pins, signed by "S. Tonocelli," virtually same type of full engraving as SO4, but with gold inlaid crown on top behind lever. Any learning on these engravers or SO guns generally would be appreciated. By the way, has anybody else exprienced the lousy support (actually non-support) that Beretta gives to these fine guns?
