MM wheel weights? Trade?

I'm moving this from the general tractor talk board,

My coworker gave me a pair of wheel weights that my best guess is that they are for a Minneapolis Moline. I was going to use them on my Massey 202 with a home made adapter, but my friend suggested trying to track down what they are actually for in case they are worth a lot more to someone doing a restoration than me just using them as weights. I guess I'm not really trying to "flip" them or anything (they're about 500lbs a piece!) but if they are indeed something someone wants I would be more than willing to figure out a trade or something so that I could potentially get the correct weights for my Massey. Otherwise if they are a common piece or something no-one desires, I would like to know so that I don't feel bad fabricating an adapter of some sort.

After cleaning the tags a little more, i can see that the tag reads,

MM
FT652C
U.S.A.
1431X

Searching that part number brought me to another thread,

But I still have a tough time finding any google image search that looks like them, especially the 3 bolt pattern, (or 6, however you want to look at it)

Thanks,

Those look like G series weights. They would fit GT, GTA, GTB, GTC, GTBD, Gvi, G704,5,6,7 etc. They would also fit the MF counterparts MF95, 95 super, and 97 as these were MM tractors as well. I have a few of them already, but could use more. I have a Gvi project tractor that when done will need lots of weight to hold it down. I currently have 4 of these weights on it which makes it weigh 12000lbs. total. Unfortunately shipping these weights are cost prohibitive because they are so heavy.

Where are you located?

I am from Ceedar Falls, Iowa. But I have a network of friends and family throughout most of the midwest.

Didsbury, Alberta, Canada. Google maps say 1430 miles NW of Cedar Falls. Between Calgary and Edmonton. Road trip?

How far are you from theif river falls, MN? The family farm is there, 500 miles north of here.

One thing, gas is cheap.

Yeah, I don't mind transporting them some miles. Like I said, I just want to make sure I'm not going to be using some rare weights that someone really really wants for their MM tractor when I could trade or whatever for weights that are (probably) much more common for my MF202. Plus then it would save me from making an adapter.
