Please help me. I have inherited violin from my grandpa, he had it for decades. He said it is very old, he bought it for golden ducats from a good violinist. Someone told me it is Klotz because of symbols imprinted on its back. Please help me and tell more about rough estimation. I have heard that original Klotz violins value from 5K euros to even 10-15Ks.http://www.flickr.com/photos/133490948@N04/
