Dewey, very nice work, lovely shapes and curves. Neat little video as well, you can see in it how easy and smooth that gun is to open. Very nice.

The Max Ern roller on mainspring was also used in the Dickson trigger plate lock, I think McKay Brown uses the same system.

As far as the removable trigger group goes, I think it is a great idea. Having a gun where the difficult to repair parts are easily removed in the field for servicing or inspection and cleaning is very handy in the middle of the bush. One of the many reasons that I drive a LandCruiser, easy to repair in the bush if you need to.

Waidmannsheil.
