Here's the way I understand it.
First character is a letter corresponding the month; A=January, B= February, etc. Second letter is the last year of the decade produced; 1= '41, '51, '61, or '71.
To get the decade right, there are some other things to look at. Here's Craig's summary of how to get the decade right: http://www.jockeyjournal.com/forum/s...5&postcount=18
Mods, sorry if a link is not OK, but in this case it seems helpful and appropriate.
I'm sure I'm not totally right, and one of the old smart guys will be along to fix up my answer a little better. (paging Rubone!)

Early gearboxes do not have "serial numbers". They have casting numbers, and from late '38 on have date codes. Early date codes are a letter and a number, from late '49 they are two numbers. There are anomalies though, like the 3-3 code used for many years in the '50s. In the '60s they began to have another number, often called an "anti theft" number on the front face near the plunger, and it also helps with dating. What numbers are you referring to? And as stated a picture would help immensely.Robbie Knight Amca #2736
