Catalog of S&W 3rd edition lists the following 3-alpha-4-digit serial number ranges
January 1988 AYExxxx-AYMxxxx
July 1988 BBFxxxx
October 1988 BBT2293
So I guess AZC3162 must fall in the same February 1 - June 30 period of 1988 as your model 36, but this one is probably somewhere in around the earlier end of that time range.
