Silver salt & pepper set

Please help me to identify the manufacturer of my salt & pepper mills. It was made in Italy but the sticker on the bottom is IFS (Israel Freeman & Son) Italy. ISF was founded c1928 in London, England. Is there a branch in Italy? Also, the bottom engraving is marked P M at the top, xxxxxxx on the bottom of what looks like a stippled triangular tree on top of a small urn. Look or sound familiar to anyone???[/img]
