I'd like to get at least another pair of these. There is no part number. Only a date code of 8 June 1954. These were installed on my W-400. Weight seems heavier than a row crop weight.
Measurements are:
5" center hole
10.625" bolt circle
16" outside diameter
Will a Farmall A weight bolt up? If so, did the later 100-140 use this weight as a replacement for the earlier weight. If the dimensions are the same, the difference would be that the W-400 weight is stackable.
I could buy or trade the following weights:
Farmall C, H, M, and later rear weights
660 rear weights
9 series rear weights
H, M front weights
Cub rear weights
Cub front weights
Maybe even SMTA-450 frame weights.
