M&C Sterling Silver...anyone know this one??

[kearney]

Hello...

I was wondering if anyone knew anything about a company called "M&C Sterling"???

I am considering purchasing a C-Clasp brooch that is marked "M&C Sterling".

Based on what I know about jewelry, I would date the piece to early 1900's.

I looked thru the database here and can't find this mark.

Any info appreciated. Thanks!
