12 ga SXS barrel

12ga SXS barrel made by Gustav Genschow & Co.  A.G. Hamburg Germany.

Geco Stahl marked on each side of the barrels

74.5 cm long ( 29 3/8 inches)

No rust , clean bores, quite a few proof marks etc which I don't understand. I acquired this in a parts lot I bought, wish I had the rest of the shotgun but not there. 

$100. plus shipping.

If someone had the receiver and stock to go with this I'd be very interested.
