I am a new member 2nd post. Note the red plum color on the upper frame and extractor. Question: this S42 is all matching assumed original but unproven, the main frame serial number 922 (W below) is not centered by one digit to the left is this usual for a number with less than four digits?

Well, my usual copy and paste failed to paste here. Photos later when I learn how.
