Raleigh Serial number. The bike is a women's Raleigh Record and was.

I posted this once before and someone answered it, but now I can't find that post. Apologies for asking again. Concerning Raleighs: how do you date a Raliegh from its serial number?

A buddy of mine has a Record identical to mine, but it's not a Notty. I think it was built in Canada or Korea. The serial number is stamped on the left rear dropout.

Mine's on the rear of the seattube. I just can't remember the sequencing of the numbers and letters. But from that original thread I learned my Nottingham is a 1974. Pls help thx.
