The tailpiece appears to have a slant from bass to treble, and a thin top bar. After some deliberation,I don't think this is a Martin, Gibson, Kalamazoo, or Bacon. The headstock does not look wide enough for a Kay or a Harmony, which in any case one would expect a little obvious white celluloid on, as one would with an Epiphone. The body looks about 16" wide. My best wild guess is that it's a Stella.
