In perusing the Alfa Catalog that Lancaster so kindly posted, I saw the illustration and description of a M-S rifle chambered in 5.6x35. It is on pare 337, and is listed as RG 35. It may be the Model 1911, although that is not clear to me. The cartridge appears to be a rimless version of the 5.6x35R Vierling, aka. .22 Win CF.

The rifle has a 3/4 length stock similar to an African model Mauser, and weighs 2 Kg. It appears to have a miniature action, although this may not be correct. Does anyone have additional information about this intriguing rifle and cartridge combination?
