But I'm back now, with a newly acquired Clubman to boot, which I'm very happy with, and drives and feels exactly as I remember a mini should!! It's been too long

Quick question though regarding VIN plates / commission numbers: Obviously during the pre-purchase once over I made sure that the car presented matched up with the V5. There is the usual black / silver oval-ish shaped plate at the front of the slam panel with the vin number as per the log book stamped into it - but thats it.
Should there be a commission number too? My other mini had a red tag stamped with a number, which was placed to the side of the vin number - should the Clubby have the same? I cant see anywhere on the log book that has a commission number - can I find this out from anywhere??
My other mini had the VIN number stamped into the bonnet gutter too - but this doesn't seem to be present on the Clubby - I've checked that it's not just been painted over or fillered, and it's definitely not there. I'm "informed" that this was only done from the early 80's onwards, so mine wont have it (it's a '78) - can anyone confirm??
Sorry for the 20-questions, and thanks in advance :)
