David,
To find out what year it was shipped we will need the serial# that is hidden under those very large and ugly (to me) stocks. The serial# is on the flat area on the very bottom of the "butt" or grip frame. When you open the cylinder, have a look on the frame and let us know if you see any stampings like MOD 10-7 or something similar. The correct stocks that came on the revolver from the factory look similar to those on the revolver in the post above yours.
