Help identifying this vintage looking gem! No serial number?

Hi all, was given this vintage looking gem from a friend a few years ago with the intention of my father cleaning it up and restringing it. We have no idea how old the guitar is and cannot find a serial number on it at all. Looks possibly 70s or 80s. Would love some help if anyone can identify it’s model, serial number and year of make! Thanks :relaxed::+1:

It’s a bit difficult without a serial number, sorry!

Have a look at the back on the rear of the trem cover for a stamped serial #.
