THAT is an outrageous lie Joe, and you should know better. L.F. Cox sent me an email probably 8 years ago asking if I had any Damascus guns. I explained then that I had sold most of my vintage SBTs and doubles to finance our Guatemala ministry, including a damascus Parker GH, and briefly had no damascus guns.
I shot my 1906 OE 16g Smith yesterday at Ben Avery with 3/4 oz. handloads, and have done so every week since Spring. Ken Marburger refinished the "2 Iron Good Damascus" barrels.
