What company made a H press , red in color and had a big letter H inside a C as its only markings?
Fuzz

I think it was C&H. C.H. was the initials of the founder, Charlie Heck. I think that was his last name. I'm not sure they're still in business though.
This is from the latest Gun Digest I have, 1996.
In looking up C&H, the say go to 4-d Custom Die Co., 711 N. Sandusky St. P.O. Box 889, Mt. Vernon, OH 43050-0889. Phone # 1 (614) 397-7214.
AFAIK, that info is correct.
