Mike at one time I had a similar style. I had ended up with two custom (made In Germany) mauser barrels. One shaped like this with the addition of a fancy full rib and folding sights.
The other the opposite Octagon to round and again the fancy rib and sights and also a claw mouth. So yes have seen it before. Smile Whitey
