Is there an online sight about violin makers that anyone knows of? I found a couple of violins that seem unusual. One is made by Joh. Bapt. Schweitzer. It says: fecibat ferman Heironymy Amati, Pestini 1819 on the label. Which I assume means that it was a copy of a an Amati made in some city by the name of Pestini??? Is Schweitzer a Swiss name? Then I also have one by someone named, Geronimo Barnabetti. Above his name is initialed J. T. L. and below it simply says Paris. Then I have another that says Antonius Stradiuarius Cremonensis, Faciebat Anno 1730. It's all Greek to me. Perplexed
