so is it fair to say that not all cello style purflings are french, but most french inst. will have it? in reference to the pics ken posted, is the one with the extension the one from france? the purfling looks rounder than the other.
is it possible to narrow down its orgin (the bass in question) with the beech neck, or is that more of a "german school" thing?
sorry for the blizzard of questions and thanks for the insights, kurt
