Pretty sure you're both wrong. I believe USFA sent a select number of their guns to Turnbull for a limited edition run. The serial numbers start with DT for "Doug Turnbull". I've got a pair of them, and have seen about 6 or 8 others for sale at various places, some with engraving on the cylinders, some without. When I get a little spare time, I'll take some pics and post them next to my 3rd gen. Colt for comparison.
