The Hydramek Ford Valve Tool Set.

I picked up this tool from an estate here in Bothell Wa, trying to find more info on this tool the rarity & value. I do not have a flat head so I have no use for this tool.
It was made by TCM Manufacturing Company, INC. Maywood, Illinois.
Model # TCM 100

The TCM 100 Ford Valve Tool Set contains all the necassary tools for quick & easy removal & replacement of valve & guide assemblies in all ford V-type Engines, including Mercury & Lincoln-Zephyr, as well as Ford (late) & Ford-Ferguson Four Cylinder Engines.

Thank You!**)
