Ok so it's request time again, having been updating the register again, I keep finding little pieces of that jigsaw puzzle, but I'm still quite a few bits missing but with your help well get the complete picture.
New dating findings
Dating your jeans through the VIN, all our jeans for the first series start with 1142, which basically means "beetle (1) saloon (1) 1974 model (4) made in the 1970's (2) now the next series of numbers are of course unique, but by using the next set of three after 1142 you get the day the jeans was built.
The numbers below only relate to the jeans model built in Belgium, German built jeans well their numbering system isn't as precise and the dating process isn't as easy.
051 = 4th September 1973 first day of production
055 = 18th September 1973
057 = no records found (yet)
059 = 2nd October 1973
211 = need more records to verify
212 = 9th October 1973
214 = 16th October 1973
215 = need more records to verify
216 = 23rd October 1973
238 = 8th November 1973 last day of production
I've also found something interesting with the last three digits, but until more numbers come in, I'll keep it under my hat.
So if anyone would like to share with us the day your jeans was built, it would help immensely please only post any of the above number not your full vin, if you would like to give your full vin for the register only please email me
