Question on my 71 Commando

There was a post recently concerning a 72 Commando, and whether it was a Combat

This got me thinking about my 71. I call it a 71 because that is what I believe it to be. But, it is titled and registered as a 72.

The bike has 9,000 original miles on it, and was a single owner bike before I purchased it. It is a survivor, and I have painted the tank and side covers. I also have removed most of the aluminum covers, fork legs, and front bake parts to polish at the shop. But, the engine has not been apart, nor removed from the frame. Silver barrels, front drum, and 930 Amals.

The VIN is 147215. All numbers match.

I know there are other places to research this, but thought someone may have some insight

Thanks

147215 is definitely within the number range for a '71 model year. '72 started with 200xxx. Your engine has a crankcase breather on the drive side crankcase at the end of the camshaft.
