With the Walther barrels, the drill is to work out your external dimensions with Woody Woodall, at Walther Precision Tools, at Cummings, GA. Then he sends your order to Germany, and it comes back to him. Unfortunately, a lot more comes over to him at the same time. So they can get bogged down separating and unpacking your small order. Woody told my on the phone that these Air Freight shipments have to clear customs and run $30K or so.
Since I was making a copy of P.H. Harry Selby's 416 Mauser, I went so far as to order a custom Bavarian 1500 profile. Woody made one change before he would accept my dimensions, and place this order. BTW, my copy uses a wildcat 10.6mm x 375 Ruger, instead of the really large 416 Rigby cartridge.
My barrel came as a profiled blank, and it was very highly polished. This paid the freight for my G.S.'s turning and threading the barrel shank for my Mauser action. It was an unexpected cost savings, for me.
