I came across an old KB&B - are they of any note? It's actually a neat little pipe. Like a miniature Bing with a nice blast.
The KB&B in a clover is the standard company logo. Any other descriptors, like "Rivoli", "Sicilia", "Rocky Briar", etc?It has the clover leaf looking stamp and the white circle on the stem. Family history would place it around 1900 to the 20's to my best guess.
