I have a full box of these Dunhill Dri-Pipe Tubes. I am not sure where I picked them up but I was going through some stuff in the drawer today and came across this piece of pipe history. Anyone have any ideas on the time frame for these? The box says: “This absorbent tube is designed to provide a clean dry smoke. It is ideal for wet smokers and should be changed frequently.” The box has 100 tubes in it. It is marked Alfred Dunhill Ltd. 30 Duke Street, St. James’s, London, S.W.1. I love old stuff like this and I am always keeping an eye for it. I believe these were to be inserted kind of like the more modern 9MM or 6MM filters or even the Medico or Dr. Grabow filters. I figured I would post them on the blog to see if anyone has seen them or has information on them. Just another interesting piece of tobacciana

Hi Steve – here is what I know about those filters:
The Dunhill “Dri-Pipe” Tubes were produced up until the early 1960’s. I don’t have a start date, but was told by James Barber in the UK, that production on these filters stoppped in the early 60’s. Personally, I have an early 1960’s Dunhill Bulldog that uses the Dunhill “Dri-Pipe” Tubes (filters).
The “Dri-Pipe” Tubes are 3mm pipe filters. As you’re aware, 3mm pipe filters are not common in France, Italy, UK or the US; as most of the common filter pipes are 6mm or 9mm. However, 3mm pipe filters are more common in Germany. There is a German manufacture, Denicotea.de that produces both 3mm and 4mm pipe filters.
The Denicotea 3mm filters are the modern replacement for the Dunhill “Dri-Pipe” Tubes.
This may not be a lot of information, but I hope this is useful for others.
Cheers!

I love this old stuff, too. The KleenReem booklets are great as well.
