I just received an email from Bromptons Auctioneers about an Omobono Stradivarius that they sold recently by private treaty. I was Looking at the picture supplied of the violin, and realised that the f-holes are very noticibly asymmetrical with regard to there positioning. The right hand f-hole is higher, causing it to almost butt up to the purfling on the treble side. I googled his name, and sure enough, he did this more than once. In the past I have seen this feature on other Italian violins. What,if any,is the purpose in doing this?
