I just sold a nice S&W 25-5 nickle in .45 Colt (auction side here), it had one of the alphabet ser. #'s (AYJxxxx), I have a S&W 25-5 blue in .45 colt with a N ser. # (N 658xxx). Why the different type ser. #'s on the same model ?

The S&W 25-5 was produced from 1978 to 1988.
The S&W 25-5 #N658xxx was produced in 1979/1980
The S&W 25-5 #AYJxxxx was produced in 1988
Also some time in 1988, they went to the M25-6 when several engineering changes were adopted, a new yoke retention system being one.
With numbers in each position, you get 10 possibilities. But, when you go to alphabetic, there are 26 possibilities.
With the old numbering system, they couldn't exceed Nxxxxxx without going to 8 positions (& requiring some new stamping presses). With 3 leading alphas, the possibilities are 26x26x26x9x9x9x9=? . (Too early to do the math in my head.)
