According to Greeners book the gun was built in 1893 and if it has steel barrels this would be a plus as most Greeners of this period had damascus.The gun sounds like a medium quality gun of the period.The barrel length sounds a little suspect,ie possibly shortened, so they should be measured to see what choke is there plus what the bore diameter is relative to the 11 proof mark. The other factors that affects value are the stock dimensions ie. drop at comb and heel. If the drop is not excessive and the barrel length is original,good barrel wall thickness,then the price sounds realistic IMHO
