Morris Minor Owners Club

Mike.
According to 'The Bible' the only Minors to have a detail line on the wheels were early low-light Series MM's. The wheels were always body colour and the detail line was always cream (debateably pale grey) to match the coach-line.

Forgot your car is an Oz ex-pat. Maybe peculiar to CKD/Oz assembled... or a former owner who fancied emulating the MM look

Mind you, the wheel you've pictured doesn't look like an original Series11 Minor wheel anyway so I wouldn't rely on it giving you much clue as to the original colour .......

MM in what way? It has the factory hole for adjusting the brakes. I had believed that was the principal difference, but please correct me if belief misplaced.

Just looked at the bible. It says that Series II wheels were the same as Series MM i.e. studs but without the brake adjuster holes. These ones have the holes but no studs. Apart from the hole it looks like a standard Series III wheel. Ray goes on to say of the series III where 'Unlike most Series II models. Minor1000 wheels have contoured moulding ....to locate the hub cap.' So perhaps some later Series II had Series III type wheels but reverted to a brake adjuster hole as well ???

My SII wheels have the adjustment hole and pins, rather than mouldings, to locate the chrome hub cap. But there are lots of deviations in production, presumably to use parts up - e.g. a 1956 Minor 1000 I once owned, had SII seats and two wheels with the pins and two with the mouldings!

What size is the valve stem hole? It looks like half inch without the bump required with the bigger hole. The smaller hole makes it about 59 or newer.
