1937 S/42 Help with ID

[Johnny Peppers]

A 1937 S/42 in the no suffix block should have all blued small parts. The extractor would not have been strawed even if in the strawed range. Production of the 1937 S/42 started in the p suffix block and the strawed parts ended in the t suffix block.

Look inside the sideplate, and the first two digits of the serial number should be found there.
