It's got salt wood if it has rust under the barrel. This was a problem from 70-74 60's I believe.
It should knock off 15% or so off the value, but alot of folks pass these to unknowing buyers for full price.

Salt wood was 1968 until 1975,with the real problem years being 1969 through 1971.
And knock off more like 50% off the price.Ask me how I know......
