Dash numbers on the S&W 586 revolver?

Recently cussedemgun gave what the engineering change dash numbers meant on S&W 686 revolvers in another post. Does any one have the engineering change dash number information for the S&W 586? Many thanks.

The changes are the same, as the guns were built in the same time frame.

Thanks for the info. I did not realize they came out at the same time. I had always thought the 586 had preceded the 686 by some years as was common on other S&W revolvers.
