Need help identifying mystery guitar

Howdy folks! Not sure where to ask about this, but my friend has this mystery guitar with no maker’s marks or serial number whatsoever. Obviously it’s been heavily modified with electric guitar components and various inlaid bedazzlements. It has allegedly been passed through at least three previous owners. My friend is not a luthier, but he knows his guitars; between the two of us we reckon this guitar was built in the early nineteen sixties based on the components, wear marks and discolouration. What do you guys think? Is this the right forum for this sort of question? Any insights are welcome!
