@ kiel, I am in awe of those pipes. What is the length, height?
My collection finally caught up with this old thread. I really like this pipe, I got it at the Chicago show this year, it is a Fribourg and Treyer.
Those two towers I posted are both around 6.8cm tall (≈2.75in). The top one is 20mm diameter bowl and the bottom one is 18mm. So that's like a little bigger and a little small than 3/4in.
I inherited this dan pibe from my grandfather. He and a bunch of other yahoos used to take an annual canoe trip on different Canadian rivers. They'd load their canoes onto trains which would take them way up into the Canadian wilderness and drop them off stream-side with canoes, whiskey, some dried goods and fishin rods. One way out.....downstream 2-3 weeks. This was his canoe trip pipe. She'll burn a while.
