Let's see.
The barrels are rusted & pitted the entire length, the wood finish is flaking off.
I say repair this gun and save it from the neglect of the past.
I fully understand keeping a gun all original if it is in decent shape, but used as intended.
I don't understand the American love affair with rust & wood with no finish.
One of the main topics here over the years has been how to save these old guns by re-finishing or re-storing them.
The best posts I remember were the ones by Dr. Oscar Gaddy & his meathods of how to a save these guns. Rust never sleeps!!
