The different concepts of what constitutes a particular shape makes for an interesting discussion.
Does a notable manufacturer define a particular shape.? Billiards have been around long before Dunhill became famous.
Did the very first carver or manufacturer to produce a named shape define that shape?
The Dublin shape had been around in many variations long before the pipemakers of St Claude begun using briar.
Is a shape defined by what the smoker or collector sees in it? If the owner sees a Prince shape in say a squat Apple, does that make it any less a Prince?
Is a handcrafted pipe a particular shape because the carver says so?
Many of the shapes we are now familiar with were developed or at least named in the early part of the 20th century.
A look at many of the retailers sites will reveal a multitude of different names applied to similar shaped pipes. Some are so far removed from what we commonly accept as a defined shape, that we begin to wonder if it some sort of a typo.
The human eye can easily pick out a change in dimension of as little as 1/64th inch, probably smaller, but that is about as small as I can go without my glasses.
Variations are inevitable, but does this variation define the shape or define the style?
Mike M's Author/Rhodesian is a good example.
I see an Author shape and Greg Pease sees a Rhodesian.
In my often distorted view of things, the rounded edges of the upper portion of the bowl differentiate it from the straight edges of the pipe in the upper picture, which was described as a Rhodesian.
I am certainly not suggesting that Greg is wrong and that I am right, but would like to use this as an example of the difficulties involved in describing a pipe as particular shape, especially one for which a specific defination does not exist.
I think that shape charts and definations can best serve us as a
guide to what a particular shape
generally looks like.
