Just purchased a 20 ga. 00, fw, 2 barrel set, 2 forends, all same serial number armor steel barrels, gun is very sound but has been used abundently, trying to decide whether to refinish or just use it as it is, will probably have to refinish stock either way, not much finish left on wood, would this diminish value, gun is certainly not a collectors piece as it is, metal is turning a brown patina, I gave 1200.00, do you think i paid to much, will not hurt my feelings
