These were in a fire some time ago and are basically being sold as wall art now.
The single barrel is a Winchester model 37 16 gauge
The one to the left of that is a Winchester model 24 double barrel 16 gauge. The one to the left of that is an old Hopkins and Allen 12 gauge. The set of barrels with no reciever is an unknown manufacturer but looks like 16 gauge also. $100 buys them all. Would like to sell all together at this time unless there is a buyer for each separately for $30 each. 817-659-6074
