So in my search for my pops, $600-ish should be about right for the Trapper model?
Add at least $200-300 in another pocket just in case.
Rossi Trappers will be cheaper than the Winchester or (gulp) the Marlin Trappers.
Typically I've found that the Trappers, being fewer and farther between, seem to hold higher values than your run o the mill 20 inch 94, all things being equal. Pre locks will run even higher.
