686 no dash AJR1852 for the serial number. If I am reading the box correctly, I believe it was made in 1985. Wasn’t crazy about the grips, but it feels good in the hand. I like the old wood ones better. The original box came with a hand written letter to smith asking for the repair work. It’s marked with the M and someone wrote M on the box. It was a lady from Michigan, that stated that the gun was for her personal protection and for swift but complete work on it. Hand written letter! Let me know if you can share anything I am missing.
