I own several Deerstalkers as well, both 54's, one flint, one percussion. They are made in Italy by Investarms to Lyman specs, and are well made rifles. I have taken a number of deer with mine, and am happy with the performance. The Trade Rifle is similar to the Deerstalker, except for the brass fittings instead of blackened iron, and I think that model has a curved but plate as apposed to the Deerstalkers flat rubber recoil pad.
