OK guys without a letter I've hit a dead end so far in my research on this particular Model 686-5 with 7 shot cylinder, 3” barrel, round butt, bead blast finish, red ramp front sight and white outline adjustable rear sight, Unless I have missed it in the 4th and 5th editions of the book of standards, and other sources. The serial number shows it to be a 1999, And I believe it to be an Ashland distributor gun. but I have no proof of that so far, so feel to jump in and help me on this one....
