I was just guessing...it has that shape. Holm marketed a
bunch of different lines...all with different names (see Cortez's post).
My experience is that some of the pipes are good smokers and some are not. Typically, they will have wide, deep bowls that hold a lot of tobacco. Most are on the heavy side if you are a confirmed clencher.
Sometimes they have a generous draw and other times they won't pass a cleaner without noodling it around a bit.
I have one that smokes wet and gurgles like an aquarium bubbler.
They were pumping out a lot of pipes at the peak of the freehand/Danish revolution and I think the QC got away from him at somepoint.
I think they are beautiful. The grain, stain, shapes....I don't know why, but I love 'em all.
My first expensive pipe was a
Golden Walnut I bought in 1977. I never looked at other pipe makers very seriously ever since that first Ben Wade.
I see I may not have answered ol' Noble's question, but yes, the key to getting a Holm era pipe is the "Made In Denmark" stamp.
