I have 2 US made SAA NIB, 7.5" 44-40, with polished hammers. I live by Classic Guns in Crete IL which will case color the hammers for $50 each, which is very reasonable. I your opinion would this decrease the value of the guns. One has a bare code label on the black box with SN written on the sleeve, the other has no barcode label on the black box but the SN and information is written on the sleeve. Thanks
