From a friend Chuck:
"Do any of the Model T guys have any info on the CURKO valve grind tool kit? I am looking for the small can of compound so marked that goes with it."
I said I would ask. Thanks
Just as easy to by a duplex can of Clover grinding compound.
I think he is trying to put a period kit together.
Just strip the paint off a Clover can and re-brand it. That's probably what Curko used anyway. It's not that hard if you have a computer and printer. The hardest part is getting the Curko logo, if it they had one.
