I don't do my own repairs, so if you intend to fix it yourself, I'm not of much help.
But if you were curious about the age: with German trade violins that have English-language labels, you can at least get a date range from the text on the label.
"Made in Germany" would be either c.1880-1939 or 1990-present. Prior to around 1880, most German trade violins weren't labeled with the country of origin; from 1887 onward, they all were, because violins imported to the UK had to be labeled with country of origin from that year onward. Also note that there was no country called Germany before 1871.
"Made in West Germany" would be 1946-1990. East German violins were labeled "GDR" or "DDR".
In 1945-1946, right after the end of WWII, violins made in occupied Germany were labeled in various ways, for example: "Made in Germany, Western Zone" or "Made in Germany, US Zone" or "Made in Western Germany".
Thank you very much for this info. The case looks Victorian, and I know a little about the history because it belonged to a friend who is now very ill. She told me it was very old and a family heirloom before she got sick. I will try to find out more if she is up for it, but I don't want to trouble her needlessly.
How would one go about finding a reputable repair shop?
