Does someone know, or would someone point me in the right direction:
How many violins have been constructed? How many are extant? Do we have any numbers from the biggest violin factories (historical and modern)? How long do violins last? How many instruments can a 3 person workshop produce in a year? 7 person workshop? 20 person workshop? How many people have been employed in the largest operations? What is the history of mechanization in the industry? What are the different ways that quality and quantity interact?
Or anything along any of those lines.
