Further Update:
I have found that the MKI (V80) did not have 8" rear wheels like the MKII & MKIII did.
In fact, there is a subtle difference to the casting of the base plate, that allows for the big wheels on the later bases, if you put 8" rear wheels on a MKI base, the rear left wheel will jam against the base at high cutting settings.
It can be seen here:

The base to the right has a round allowance for the rear left wheel, this is the MKI, the one on the left has a more chamfered allowance, this is a MKII base.
