I want build a copy of Stradivaris viola d ́amore 1727. Can you someone know, where can be find some photos, plan, where is this instrument now (some museum or owner) ? I find only Stradivari sketch in Sacconi book and some photo on http://dipperrestorations.com/the-stradivari-viola-damore/     Have you someone experience with building of this very nice instrument?   Thank to all!
