Frames were made and serial numbered in sequence, but finished revolvers using these frames were not completed in sequence. A low numbered frame may have been used long after a higher numbered frame in the manufacture of a revolver. For example, 44 Magnum, S166065, was manufactured on March 29, 1956 and shipped on April 2, 1956, whereas, 44 Magnum, S153810, was manufactured on November 5, 1956 and shipped on November 8, 1956.
