My great grandfather's old violin

While doing a bit of cleaning through my mom's office, we found my great grandfather's violin. According to my mom, my grandfather swore it was a Stradivarius, but she's pretty sure he was wrong. I saw no kind of identifying marks or anything on the inside.

I was just curious if any of you could tell me anything about it, or at least point me in the right direction, it's well over 100 years old at the very least, as my great grandfather had it for decades before my grandfather was even born, and he was born in 1902, and I'd love to be able to uncover some history about it.

Thank you again, and apologies if this isn't the right subreddit to post this kind of thing.
