I can't speak to all the DT guns, but the pair that I bought exhibit all of the US produced characteristics, at least as far as I can tell. Got them in 2012(?) if I remember right. Consecutive serial numbered, 7 1/2" 44 WCF black powder framed. I remember asking for the BP frame, they threw in the consecutive numbers just cause they had 'em on hand. Fantastic pair of handguns.
