Shane no production information for Lefever guns remains but by extrapolation this gun was made about 1904. The twist barrels show plenty of contrast and there are good colors remaining on the water table so I would say it has seen realativley light use and has been pretty well cared for. If you can get it right go for it. You will not be able to use "modern" high pressure loads but companies like RST make low pressure ammunition suitable for damascus and twist barrls that are effective for clay target shooting and upland gamebirds.
