Just picked up a model 36. It is in very nice condition but I cant find when DOB is and need an experts help. Says mod 36-3 when you open the cylinder. Serial number is bna4021. It has many other markings and things but I have no idea what they mean. Also its a 3" barrel. Any help is appreciated.

The SCSW says 36-3 was done in 1988 but your serial shows 1993. I am sure someone else will know for sure. Sorry I could not be more helpful.
