It has a label that says “Antonius Stradivarius Cremonensis Faciebat Anno”. After I got it together, I took it to a violin shop in Berkeley Ca. where they made a bridge and a sound post for it. They confirmed that it was German from around 1870-1880. These are fairly common. It only has a double line in the front and back. The tail piece has a nice silver wire inlay. It also has an 1911 repair marking. I was to take lessons in the late 60’s, but it was already broken. My lessons were delayed 50 years.
