The stamping should be:

M1
0

for 1971

and
M1
9

For a 1970

M = Motorwheel company
1 = Plant #
digit under the M indicates year it was made

Your "M" stamping looks like a double hit or a mis-stamp? The date is also stamped inside the rim area covered by the tire, look there to confirm. It's also possible that it has no year date stamp, some VERY early 1970 production wheels came that way. If you don't need it I know a guy who needs an early on like that for his super early build date car, PM me and I'll give you his contact info.

Thanks for the info. When I get a chance I'll dismount the tire to verify date.

tire
U - 1969
A - August
9 - ??
1 - Akron, OH Goodyear tire plant

wheel center
M5/9 - Motor Wheel plant #5 (Canada) 1969

wheel hoop
2944450
M1/9 - Motor Wheel plant #1 (USA) 1969
8 -o- 21 * - Thursday, August 21st

You can see the top of the "9" in the first pic. I find it odd that the center is from CANADA and the hoop from USA.
Anyone have a "450" wheel they can look at to see if this is the norm?

I looked at a couple of mine and yes, that is how they are on 2 that I just looked at.

Here are some pictures of my 10/14/69



I also looked at one of my 1-15-70's and it had M1 on the hoop and M9 on the center also.

Thanks for all the info. Was out this morning in the garage and took a look at the 4 15" rallye wheels that came with the same car as the 450 wheel and there all date coded M19 8 12 So I'am thinking maybe these wheels all came on the same car and the 450 wheel was the spare ? The tire being a F60-15 on the 450 wheel would most likely indicate these were off a B-body ?
