I recently picked up a ladies Raleigh Record for my wife with a similarly formed serial number. I found your post while trying to find a serial number decoder for these mid-80's bikes. My wife's Record's serial number on the underside of the BB is 4DJ15... the rest is obscured by the plastic cable guide. I *believe* the first number in the serial number is the last digit in the year of manufacture, and I am only basing this on finding the men's version of her bike with the exact same silver and blue w/blue cables color scheme in a 1984 catalog. I have come accross others in these who have posted their serial numbers and catalog finds, and it appears that the "first number is the last digit of the model year" seems to hold true. This would mean that your bike is a 1983 based on the serial number fragment you provided. As to what the rest of the numbers and letters mean, I have yet to find out. My guess is the rest would somehow denote the location and month of manufacture, and the last four digits the serial or sequence number of the bike.
He's hoping one of us finds something more specific out!
