10.25 X 69R EXPRESS

Relatively rare cartridge dating from around 1883 and first shown in the 1886 Export catalogue. It was introduced by Lorenz as case #214 and still offered in the 1904 catalogue but not after that. The A.HEEREN * Y  MASSA * headstamp is the only known one in this cartridge. It was likely produced by DWM for Antonio Heeren y Massa who was a German gun designer. (Dixon Ref: GSP44)
