There were two forms of Newton Mausers. The first was imported in 1914 and to date no specimens have been positively identified as from the batch of two dozen contracted for. A second group of a hundred rifles were imported in 1922, all .256 Newton, with reversed double set triggers and a butterknife bolt handle. A few had a clover leaf arranged muzzle venting system. When I was collecting Newtons, I had three of the 1922 Newton Mausers, one of them restocked by Shellhamer. Bruce Jennings had two of them. They remain the scarcest model of Newton rifle. The one pictured by xausa shows a Model 1922. Several years ago I wrote an article on that model which appeared in ARMS AND THE MAN.
