The circle on the headstock reminds me of a Lisa or Mauna Loa. It doesn't have a zero fret, like a TV Pal or Islander. The nut looks very high. I wonder if the action will be high too. I don't think it has any relation to any of the 1950's ukes that I know.
If you get it strung, please let us know how it plays.
Unfortunately, I tried to set it up, and the action is much to high, and even it wasn't the frets are insignificant and dont allow for proper chording. Oh well, it will make a nice decoration.
