This is definitely a shape harkening to the 60s and 70s Danish freehand chart. Then again that isn't all that surprising given Poul Hansen relied heavily on advice from Sixten Ivarsson when he first set out to carve pipes. Originally a machinist, Poul Hansen designed and repaired machinery for a variety of pipe makers in Denmark during the 1960s. Eventually he decided to try his hand at the craft and he headed straight to "da man" for advice. While not an English-styled Dublin, this has such soft edges that, if the heel extended below the shank at all, it would nearly qualify as an Acorn.
