Weber nomenclature (was: Re: Webers)

["John Hertzman" <johnhertzman@domain.elided>]

It is generally understood that DC means 'doppio corpo', double body, O
means 'orizzontale', horizontal, V 'verticale', I 'invertito', and that as
time went on the inventiveness of the naming became more arbitrary and
difficult to follow logically. Pat Braden made a serious attempt to decipher
the system but in the end said something more or less like "hey, it's
Italian, you want logic, go north". Some of the trailing letters seem to
follow makes, the DCN becoming a DCNF on a Ferrari and a DCNL on a
Lamborghini, but an F can also be Ford, he says. So, live with it, and
enjoy.
