The first commemorative to feature the Model 29-2 was made for the North Carolina State Police in 1979 and was available to NCSP officers only. The 29-2 has 6 1/2-inch barrel, nickel finish, and smooth, target stocks. The side plate was etched with the seal of the NCSP and an additional NCSP serial number was stamped on the frame. The 29-2 commemorated fifty years of the NCSP, 1929-1979, that was etched on the right side of the barrel. The 29-2 was shipped in a special presentation case.
I have no idea what these guns may sell for, but since they were only offered to NCSP officers, you rarely see them for sale.
I have not heard of a similar commemorative in .357 magnum caliber, but I have not studied guns in that caliber in detail.
