I am the proud owner of a Simson Cape gun in 8 x 57 JRS and 16 gauge. There is also a set of 16 x 16 ga barrels. The gun is plain with no engraving or claw mounts and shoots very well. I have killed half a dozen water buffalo with the gun. I have owned this gun since 1982 or thereabouts.

Apart from one Polish cape gun in 9.3 x 72r and 16 gauge (I think) I have never seen anything similar to my Simson.

cheers
