I won a pipe rack and it came with four old pipes .As luck would have it one is a KBB shape 1514 Rocky Briar . Now for the strange part . One expects to see a four hole stinger but this on tapers to a point like a pencil .The pipe is virtually un smoked .The reason became clear the stinger when pushed in the stem cut the stem and a flap of of rubber impeded flow . The logo is kbb not kb@b inside a clover, pat number 298978 .Any idea of age .Or has anyone else seen a pencil like stinger in a old kbb .Stem marking is a double circle .Could be trash or could be treasure probably trash .
