Mike,
I also disagree, if we had a ledger compiling the info that we do have you would be able to identify trends such as which Hofbuchsenmachers used which mechanics & this would Help establish patterns on materials & Quality. We have all become to accustom to saying "I Know Quality when I see it". With compiled info we would be able to establish 1st teir retailers & craftsmen for future buyers/collectors to be able to identify.
