Acquired this vintage tool and cutter radius grinding attachment, but can't seem to find out what it belongs to. Thought it might be for a Cincinati or a KO lee but can't find any info verifying that. It has mating numbers stamped on the some of the pieces no name. Its very heavy and very well made,(no toy) I am disassembling, cleaning and painting. If anyone has any info on this it would be greatly appreciated
