I said I wasn't going to start another rifle till I got some other projects completed,.. but..,.I am thinking about a build based on 137 and trying to decide on lock choice. I've got a nice Bill Large tapered and flared .50 x 42" that I have been trying to decide on what to build around it. Have an L&R early Germanic lock that looks very close to 137's lock . A black walnut stock blank that has been drying for almost 15 years..? I may have to scratch the itch.
