Did a quick Google and found an old eBay UK listing:
ANTIQUE EDWARDIAN HFB H & F EXCELSIOR SOLID SILVER BANDED SMOKING PIPE BIRM 1907
It was a bowl only, and not very pretty to say the least.
There was an oval stamp with HFB inside on the shank and the word Excelsior was written in script beside it.
H&F might be the company name.
