A buddy of mine wants to buy a 1917 Enfield action I have and I don't know what it's worth, I don't want to shaft him but not give it away either. It has had the ears ground to match the front ring, bolt handle modified for a scope and switched to cock on closing. The bolt face has not been modified. Also includes a London Guns magnum drop magazine, unpolished, to hold five .375 H&H rounds. What should I ask for it. Thanks.
