Agree with JLDoggett, it appears to be a model number:


R. Wallace & Sons Mfg.Co. - Wallingford, Conn. - 1898


R. Wallace & Sons Mfg.Co. - Wallingford, Conn. - 1898

Ok that makes sense, what do you guys think the age of this is. I was thinkin 1920's maybe 1910's.
If you all are interested in a challenge, check out my I.D. help post I have done hours of looking and cannot find anything on this pendant I have.
