42M(b) info needed
A friend brought over a Mossberg 42M(b) so that I could help him sight it in. Nice little rifle. I have a few questions about it. Hoping someone can help out. It has a stock extender on it. Why? What's the purpose? It has a normal square slot rear sight but the front sight has four different sight blades that can be flipped up or down depends on which one you want to use. Whats the reason for the different sight blades? There is a door in the buttplate that leads to a hollow in the buttstock. What's it's purpose? Last but not least, how can I find out how many were made?

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

Solddaboat, This gun has a S 102 rear sight on it, it does have a front sight hood. The gun is in great shape and has all it's bluing. It is also a civilian.
Thanks for the info, it got me going in the right direction.
