I made that mistake and got corrected by Loxy & Speedman - they seem to know their stuff!
See: http://www.type2.com/m-codes/t2models.html
The first two digits of the chassis number do not appear on the options plate so the first digit - in this case 2 - identifies the model year, the following digit identifies its a type 2, the remaining 6 digit number is the serial number.
Gotta think about my username now... :? :?
