Stromberg-Voisinet Parlor Guitar 1920s

This is a hard to find 1920s Stromberg-Voisinet parlor guitar I recently purchased at an estate auction. Everything appears to be original, including the Kluson Deluxe tuners. The bracing looks solid and tight. The top is solid spruce, with birch back and sides, an ebony fingerboard, a comfortable V-shape neck and the original, intact floral stencils. Looks like the neck was reset at some point, with good action up and down and no buzzing anywhere. The sound is full, clear and loud. I’ve tried to show the body imperfections in the photos; the surface scratches and typical wear. On the back, near the bottom-center, is a very narrow and shallow surface crack (see photo). The bridge has a narrow crack along the center line and, after replacing a very old set of strings, I found the intonation to be slightly sharp on the higher frets. I know nothing about repairs and don’t want to begin on such a beautiful instrument. The Geib Case appears to be original…inside is a neat little sticker that reads “American Institute of Music.” Good find, even better if you can take care of the bridge repair.
