I appreciate the Lovat shape for its simple lines and straight forward pipe-ness. I mean, at first glance it seems as simple as: Cylindrical Bowl + Cylindrical Shank + Short Saddle Stem = Lovat Pipe.
However the more you consider the high functionality of the shape, the great many factors that come into play in terms of size, finish, stem material not to mention the cooling effects and absorbency of the elongated shank, this seemingly simple equation begins to morph into one of greater complexity.
Now finally, factoring in the proper ratios of bowl height to shank length, bowl height to stem length and posterior bowl height to saddle length that give this utilitarian shape a sense of balance and poise, you really have the makings of a very complex equation. An equation in which the values of A, B, X, R and Q have to be determined. An equation which really is better left to such a famously fastidious perfectionist as Brad Pohlmann. Mr. Pohlmann, engineers, mathematicians, artists and Lovat devotees offer you salute.
