serial number request
This is my first post - hope I'm doing this correctly. I have acquired a ".38 S. & W. SPECIAL CTG" serial number 520xxx (protocol suggests I don't post the whole number). The number 354 is stamped on the frame and visible when I open the cylinder. The number is duplicated on the base of the arm which holds the cylinder.
Also, I'm confused about what cartridge to buy. Appreciate any help. Thanks.
