Cool find! This is an HG-00. It was originally set up to play Hawaiian style with a slide. These guitars didn't have serial numbers but there will be a factory order number on the neck block. Look inside the sound hole towards the neck with a flash light (and maybe a mirror). There will be a vertical block on the rim inside that the neck dovetails into.

Looks to be in nice original condition except that the bridge is a replacement.
