I'm new here but not new to fiddles. Most fiddles that are branded, either Hopf or Stainer, are German factory fiddles. A lot of them from 1880 to 1910 or so had very good striped maple backs and sides. Yours may be one of them. Without a hands on inspection of the fiddle it's hard to tell the age and pedigree. Even over the web pictures don't do much good. I'm in St.Louis, Mo. area and if you're ever in the area I would be glad to see what I can determine about the fiddle. Most of the time the brand outside and sometimes inside and labels inside ordinary factory fiddles doesn't mean much. The bottom line with a fiddle as far as I'm concerned is; if it plays well and has a tone that you like, if it's worth $10.00 or $200,000.00 as long as you're happy with it, that's all that counts. Thanks for letting me ramble on.
