Nice little rifle,,can't hardly buy a bbl and lock for that price to build one.

The lock looks Ketland style to me but no matter,,I like it!
I think L&R (or one of the other lock makers) makes drop-in replacement for the DGW/Miroku Tennessee rifle should it ever need one. Miroku made some nice stuff though.

It seems like the L&R has a double throated hammer but maybe I'm thinking of another. They make quite a few 'replacement' locks.

Almost went for a .25cal (Rayl) bbl recently but have too many other projects to do. Probably just as well,,the novelty might wear thin as quickly as the bore fouled, though some say it doesn't.

32 seems traditional if that's the right word.
