I haven't had any luck in finding this makers mark. I've searched and searched. I'm hoping someone in this forum can help with identification. 3 marks of the same design with differences in each one. The mark in the middle of the trio looks like there's a C in the center; I can't make heads or tails...

I've tried to find information on these marks, but haven't had any luck. 3 marks of the same design with differences in each one. The mark in the middle of the trio looks like there's a C in the center; I can't make heads or tails out of the other two. I'd like to know the maker and any explanation ...

Thank you both so much! I couldn't make out what the shield design was. Your help is very much appreciated.

Requesting some help with identifying this mark and an approximate date of manufacture.
Is it Silver Plate or Sterling?

Thanks!
