I mainly collect Scandinavian antique arms, military and sporting, so I keep a rather close eye on the market. The high grade Husqvarnas hammer guns are somewhat hard to come by in the U.S. So it is difficult to give any type of average price. This one is not in perfect condition and I grabbed it at $1500.00.
I will be taking it out for a little goose hunting this fall. With hopes that the tight chokes will help with my luck.
