Though this long, tall, and lean Acorn shape can be found on many old English charts, it's really one I tend to associate more with the older French style. I suppose it's just one of those shapes that was translated over into the English school with less alteration than, say, various Billiards underwent. (The French had some very distinctive Billiards - examples of which are still made by Beo and Genod.) Of course, old French pipes also tended to be quite small - this towering Acorn, not so much.
