HI just to add the part number on the back of the "Mullins" 18 x 8 leg.
...dug the other wheels out and it looks like....
.
.....FORD....emblem

....8913-1007-AA....

The 4 Mullins wheels are the same...
the first number is not clear on any of the wheels....looks like 8.

There is also some sort batch number on another leg
6 numbers ending with a capital letter.
In my case, A, D, N, N are the capitals

I have a damaged slightly buckled, spare which is different again.
Ford Emblem
18 x 8J
36.5
and the part number..
....3R231007ABA...

The marks/strips on the front of the legs of the spare wheel appear about 1mm to 2mm longer towards the centre than the Mullins wheels.
Cheers.
