Hey looks good.
My bus is a 67 it has large numbers stamped in the engine bay sheetmetal on the LHS. The first 3 digits tell you what model it is.
There might be an aluminium plate on the bulkhead behind the driver seat, or on the side of the air box. Mine has a small plate on the remove-able engine cover that had a date stamped in.
I might be wrong but I read somewhere that if the rear louvres are down low it's from overseas, aussie busses had the louvres up high.
The first two of them are not displayed on the option plate, but you can find them on your registration papers and in the back near the engine. These two numbers indicate the model:
21 Van (no windows in cargo compartment)
22 Microbus
23 Kombi (windows in cargo compartment)
24 Microbus Deluxe
26 Pick-up
27 Ambulance
The third digit (the first on the options plate) stands for the model year. For example "7" stands for 1967. The model year runs from August of the previous year until July in the actual year.
The fourth digit (the second on the options plate) is a "2" on all busses. I have no idea why.
The number that remains is a serial number.
Unsure what year it is yet, haven’t been able to find VIN number as yet. Anyone got an idea what year it is?
