FS 1305 on bottom of an antique tea/coffee pot? sterling?

Was looking at this one but I don’t know if it is sterling or not, soooo I don’t know the answer to the question “to buy or NOT to buy?”

Anyone have any info for me???

Thanks so much!

If that is the only mark the odds are its not sterling. Virtually all solid silver - sterling or otherwise - carries a purity mark such as the word “sterling” on American and others, or the lion passant on UK items. Rule of thumb - no purity mark, not sterling.
