For those feeding (or just keeping up with) the data base on the early post-war commercial M&Ps, here is another data point in the overlapping serial number range between 811120 (the lowest S-prefix) and 813132 (the highest SV prefix). I recently acquired S812991, a 5” that shipped in March 1946. Like its SV counterparts, is made from left-over Victory frames as evidenced by the plugged lanyard swivel hole.
