r/ViolinIdentification

While doing some cleaning, My mom came across my great grandfather's violin and we were curious about it's age/value. All my mom knows is that he had it when my grandfather was born, so it's from at least the 1910's/20s. I've been looking for reputable luthiers in my area, but in the meantime, figured I'd ask online to see if someone might know. As far as I could see, there were no identification marks on it

Thanks for your time.

I bought this Viola in about 2010 off of eBay for $700. My mom was a lifelong viola player and played in the Stanford University symphony. She had a viola that she had played for her entire life that was given to her by her father when she was in college. Around 2010 or so the viola was stolen out of its case by a relative/drug addict. We never found out who it was. My mom only discovered it when she opened the case to play and the viola was gone. It completely shattered her. She was in tears for days. I didn't know anything about the instrument and went online and purchased what I thought would be something of a replacement to ease the pain for her and for her to have something to play. It turned out to be not the right thing for her, but the gratitude she had to me for doing that was immense. If anybody could help with any information and resale value I would appreciate it. My mom passed in 2013 and I'm finally ready to let go of it. It has a label inside which says:

Ottomar Hausman

Geigen- und Cellobauer

MITTENWALD/KARWENDEL

Made in Germany

-HANDARBEIT-

SERIAL- No. A657

Antonius Stradivarius (in italics)

Cremonensis faciebat 1719 (in italics)

1960

Old violin identification!
No additional information….
I would like to know If it could be interesting to buy it to restore it.

This was my late grandmother’s violin so must be at least 100 years old.
The label inside says Stradivarius but I appreciate that’s vanishingly unlikely to be accurate.
Any information on its history or value (if any) very much appreciated.
