Pliers with unusual symbol, no maker

[cgw2also]

 Bought these at my favorite flea market recently mainly because of the unusual marking on them. Does anyone here recognize the maker and what the symbol is? TIA for your help.

I have a pair and we discussed it here, but never came to a conclusion as to who made them.
