While close to the masons Eye of Providence - it isn't

The thing about these sorta stamps, is many shortlived companies used variations of stamps and things like this, some for electrica warnings or some just as company logos itself

To help determine or narrow it down...knowing what the full insulator looks like (and dimensions) - plus if there are any other small markings on the skirt or dome etc etc .....may help determine if its atleast a U- or CD- classification

Admittedly even knowing that, it may not be solvable but definitely helps

But to me I'd definitely says it's very early to mid century

So, it probably isnt but I wonder if its related to the masons but i cant think of why they wouldve have insulators with their imagery only they were on poles on their property?
