I am considering the purchase of a .410 double barrel side by side shotgun. The mfg is E.R. Amantino. It is in new unfired condition. From what I understand, E.R. Amantino is the same as Stoeger. I have always had a soft spot in my heart for a .410 double, but don't know what a fair price for this one is. It shoots 3" shells, and is unfired...N.O.S. Anyone have any insight?
