Ex-Riccardi Cornerless Bass Copy (formerly attributed to 'Storioni') (SOLD)

[Pino Cazzaniga]

Ken,
As you have the "real thing" open for restoration, I would trace the outlines of the plates on the same sheet of paper.
Then I would draw a centre line, and the perpendicular lines at the upper and lower width, at the C width, at the stop, at the eyes of the F holes,etc. I would also trace the given back braces.
Then I would play a bit with numbers, looking for proportions among the given measurements.
I don't pretend that this is a way to know the original maker ideas about the design, but it may be helpful to get one's own insight of a given object, and sometimes it's funny (sometimes it's frustrating too).
The danger is to cut the foot to fit the shoe...
Anyway, if something is to modify, I would do it thinking of the founded proportions (if any!)
