Thankyou for the info. Very enlightening.

kuduae, I will be trying to procure that book in the next month. I have two expos and a gun show, all in Feb, so should get lucky at one of them.

dons, The Mm410B is a lovely little thing, it comes up nicely and feels good in the hands and looks real good for a 70 something rifle. I think value of the Mm410B is similar here, I know someone that knocked back $3500 for his (much similar condition). I didn't pay anywhere near that for mine though and only curiosity value for the Ms420. I would like an original one and a single shot sporter rimfire and a rimfire "trainer" from the same period, to go with the Mm410B.

Cheers

CF

EDIT: I also have the bottom metal, screws, trigger and magazine for another Mm410B, might look about for a lesser one to build up and use.
