Hi All,
First off I want to say thanks for everyone's help. I have learned so much, including that my frame is most likely a reproduction. In fact, they really are not that rare.
One website even offers it for sale right now. It even says
These identical replicas of antique style European Sterling Silver Frames are made by casting the silver into a mould to create the 3-Dimensional raised look.
You can find the site here...
(admin edit - see Posting Requirements ) Another one on eBay, is marked Sterling Silver. The seller says that it is likely from the 1980's.


Lastly here is another with English Marks.


Correct me if I am wrong, but I take these marks as follow...
Makers Mark- William Hunter or William Hurcomb, but both seem these silversmiths seem later than City mark.
City Mark- London
Silver Mark- Sterling
Date Mark- 1817?
Duty Mark- King George the 3rd.
Finally that leaves me with my frame, with the RC and 925. I guess if you can still buy a version today, there is going to be a lot of trouble getting a date for mine. While I do not think it is as new as the last 30 years, It is probably not an original. The nice part is I still love it. I can see why they were so widely reproduced, it really is a beautiful frame.
Thanks again everyone.
Phil
