This special S/N series, marked in script with Walter Roll's initials "WR", consisted of 200 sporting rifles assembled early during the French occupation of the Mauser factory in Oberndorf ( June 1946-August 1947 ) before changing over to the standard Mauser numbering system. I have recorded 6 rifles with S/N 39, 55, 73, 103, 131, and 159. I owned S/N 131, a Type S in 6.5x57 with a Zeiss 8X Zielacht scope.
