I have an opportunity to purchase a 651 tomorrow with a 22lr and 22wmr cylinder. It has a serial of 69516. Could someone provide an estimated birth date?
You better re-check for the serial# as the number you posted isn't it. The serial# is located on the bottom of the grip frame. The first 902 Model 651's had a serial# prefix of "R" (R3XXXXX). After this the serial#'s had a 3 letter alpha/4 digit number (AAAXXXX).
