So, the order goes like this (by year of introduction):
13-1 - 1974
13-2 - 1977
13-3 - 1982
13-4 - 1988
13-5 - 1997

See here at Post #31:
Question on my post war smith and wesson 38 special
So if 13-6 was first then the 13-1?
Wat came after the 13-5?
No. The Model 10
-6 came first. Then the Model 13-1.
Nothing came after the Model 13-5. No further engineering changes were made before 1999 when the Model 13 was discontinued.
