cast iron

There is one for sale locally, but I would prefer to have Tractor with CI Rear.

I have a 32" bandsaw ca.1920, with a chip in the rim of the upper wheel. I'm trying to figure out the best way to repair, before re-tiring the wheel. Wheel is cast iron, with a machined rim and hub, and some spot removal on the spokes for balancing. Since getting it right and strong is much...

Can anyone help identify this wheel? It's 40" diameter and 3" wide. IHC stamp and numbered 8707. Thanks for any information!
