Hi Ron, according to Jan's Third Reich Luger Book, there were about 38,000 S/42 Lugers produced in 1939 compared to about 85,000 Code 42 Lugers. I have found the S/42 Variation is difficult to find in collectable condition. There is a significant premium for the S/42. I would estimate the S/42 would be about 1 1/2 times the cost of the Code 42 in the same condition.
