Mysterious Oahu Guitar

I inherited an Oahu guitar from my grandfather and I am trying to learn something about it. I am sure it is an Oahu Publishing Company guitar the stamped I do says the company was located at 850 Euclid Ave, Cleveland Ohio and the other stamp in red ink says “F33”. The guitar has a square-ish head with two slots that the string winding mech is located in and the neck is colored green and red on the feet side and rounded on the back. It has 3 green dots, between 4th and 5th fret, 6th and 7th and 8th and 9th fret. The sound board has a cool Hawaiian style coconut palms motif and the bridge is a dark grained wood and the “nut”? is a metal piece where the strings terminate and is a trapezoid in shape screwed to the bottom of the body with four small cross-head screws.

Any history and value info would be greatly appreciated.
