I found and purchased a new Cherokee/Seneca hammer yesterday for $30. They had another, and I might have to go get it, too. I've found a small gaggle of Seneca 45s that were used by the DNR for 'something'.
A few scratched and dented stocks, missing thimbles, hammers. It would be nice to buy the whole bunch to make up what whole rifles I could. Even a rusted bore/barrel still has a thimble or two, barrel lug, etc.
