Just picked up an old K-frame 38 Special with 5-inch barrel and fixed sights. I believe she was made 1948-52. Appears to be in great shape and smooth as butter. I've always wanted a 5-inch pencil barrel 38 K-frame but never thought I would find one in this good of shape. Serial number is C 199179. Could someone help me narrow down the year of production? I would appreciate it greatly.
