Hmmm...interesting revolver. I'm always pleasantly surprised when Forum members show up with revolvers that I've never seen before. The Product Code (101206) indicates this is a 6" blued Model 29 ca. 1984-1999, and the s/n (CAD1023) is for a 1995 manufacture. And if I'm not mistaken, the Spec Ord indicates a manufacture date of the 6th day of 1995. I looked through the SCSW 5th Ed. and couldn't find any references to a special product run (e.g. Lew Horton), commemoratives, or Performance Center release of a Model 29 that matches this example. The Mag-Na-Port quad porting was ordered by a previous owner (see the order/receipt for 3-14-1998?). This looks to be a Model 29-6 with standard Hogue grips and the top strap drilled and tapped. I would think it's value, if the RDO is operational, is somewhere near $900-$1K.
