I got this Dunhill pipe in a batch of ebay dregs awhile ago. The lot description said nothing about a Dunhill being in there, but as you can see it has major issues (mostly, two major cracks and a necrotic rim). I hadn't touched the thing until I needed an oxidized stem for one of my "experiments". When I pulled the stem off, I found this Dunhill branded filter. I need to do some more searching, but I have only found reference to Dunhill 9mm filters. This filter is certainly not a 9mm. Has anyone seen one of these filters? The marking on the pipe are mostly gone, even with a hand lens I have not been able to read much of the nomenclature.... -David I'm looking for a someone with poor eyesight and a Dremel to fix the pipe, but right now I'm more curious about the filter.
