Featured Help I/D ring ???military???

I Hello everyone I was wondering if any one might be able to I/D the rings sybols looks like bombs to me that is why I figured it was military and if anyone might recognize the rings makers mark that would be great as well thanks ..Matt

 

Well, with a hammer on the right, could those be nails on the left??? Could it be a Carpenters Union???? But I haven't a clue on that mark!

 

Ugh. Wondering if it could have Masonic significance, found this:

Happily, not your symbol.

 

This looks like it belonged to someone who worked with his hands & never took it off. Not farriers:

 

Interesting that the UBC emblem looks so much like the Masons' one & does not include a hammer.

 

Wonder if it used to say around the edge, but all worn down now.

 

Just want to thank everyone for there replies and the time you guys and gals spent helping me figure it out I give up for the night been trying to research it my self with no outcome anyways thanks again everyone. Matt
