And there's me thinking this was near to perfect
Looking at the pipe in hand I think the problem is the ends of the shank, it straightens slightly at the bowl and mortice and with the straight extension kinda looses it. There is not a lot of wood left to play with, roughly 3mm, so no alterations are possible.
I call it a Dublin because of the chamber shape, it is possible to make the same shape bowl with a billiard chamber.
If the answer is bamboo what was the question?
