I've read that there was a series of Doug Turnbull SAAs that were based on Colt 3rd gen SAAs. These were supposedly shipped in the white to Turnbull who applied the finish and did final assembly and sold them as Turnbull SAAs. These guns had either a "DT" prefix or suffix - supposedly 500 of each. These were done between 1999 and 2000 or 2001. Blue Book states this information. LGS has one of these but the barrel is marked "USFA Mfg Co Hartford CT USA", while the trigger guard has a stylized "DT" in place of the "VP". Anybody have a definitive answer on whether or not these were originally Colts or USFA parts guns?
