The S-101 front sight (which should have a hood) was used in conjunction with a S-100 rear peep sight (which I assume is missing). The stock extender was just a selling point to make the rifle look more military... (remember the world was at war when the model 42M's were designed and produced). The trap door butt plate was also a military type of selling point. I was used to carry an extra magazine.
42M/42MB production was 1940-43 (produced mainly lend lease to England for training) production around 55,000. No real production numbers on civilian models.
42M(a) 1944-1945 production returned to civilian market. (S-104 rear peep)
42M(b) 1945-1947 changed to S-100 rear peep
42M(c) 1947 changed to S-130 rear peep
