This is a very old archtop f-hole style acoustic guitar. It does not have a brand name and it does not have any ink stamps or numbers anywhere. Other than the paint being mat from age this guitar is in fantastic condition especially considering its age. The top is solid spruce and I would guess the back and sides are solid wood also. The neck has a nice 'V' shape to it. The only guitars I could find that look just like this one are from the 30's. It appears to be all original. This guitar is not much different than a Gibson L-50 from the same period or an L-48, L-37. It might have been made by kay, harmony, gibson, gretsch, silvertone, airline, etc. Your guess is as good as mine. Comes with a case.
