The motor number should be the same as the VIN.
The VIN is normally a plate, maybe 3" x 5", riveted to the headstock on the frame. The only numbers stamped on this plate would be the engine number and the month and year of production.
According to public sources, 1974 model year started with 307311, so you would have a '74 850, probably assembled in September-October of '73

I do not have the factory vin plate. I guess what I'm asking in how many numbers or letters am I missing? The numbers I posted are all I have and they were on the motor. How many digits are in the vin.

Should be the same, I believe.
Nortman,
There are six digits to a VIN on a Commando. It's the same number as the one on the crankcase, if it's a numbers matching bike, which it may not be. Meaning, there may be a bike out there with 307312 for a VIN. If the process is anything like California, you would start by giving the number to your Motor Vehicle Department and see if it's clear. Then buy a plate and stamp that number on a plate that you can buy from Norton parts dealers. The plate you're looking for is right behind the headlight on the frame. There are Title companies out there for this sort of thing, but I've never used one. BTW, can you see a number stamped on top of the gearbox?

Thank you for the response There is a number on the gear box but it is not the same. I also Have a 71 Triumph and the VIN is longer with a letter or two in it so I figured I was missing stuff.

Different company (well, mostly at that date) and different numbering schema.
