I posted this once before but had no one know what it is. I had absolute faith that I would have dozens of people tell me what it fits. Forum members have never failed me yet..... (yet) The letters look like "CE" or "CCC" or just "E" to me. I have seen the logo before, but do not remember where. It could be an automobile, or a fraternal order, or ???? Thanks ......
Don't know but Christian Endeavor used the CE marking, in many forms, since the late 1880's. May have been used on clamps for expression of faith.
Dan: Thanks that is one, I have not encountered before now. Ill do some more research of their logos.
