I recently purchased this estate pipe at my local tobacconist shop. It has a fairly large bowl and a long oval shaped stem. The only visible engravings are "SPECIAL" , "ENGLAND" and the number "409 DC". It is light as a feather despite its size and is one of my best smokers. Does anyone have any ideas about the pipe's maker or history? I'm thinking it could be a GBD Lumberman based on these clues.
