I have come across a Kay acoustic guitar; black; square head; model K370 (not K370D); possibly "American Heritage Series". Maybe 1965?

I cannot find any info on it. Kay website doesn't even list it as a model. Nothing on King of Kays.

Can someone guide me to the right location for information on this guitar. It seems like a good one, but I don't know.

It was pretty expensive when it came out, from the looks of it. It isn't a common guitar, and was one of the lesser-bought guitars along with the 400 series back in the late '60s. It was also featured on Jay Scott's Cool Kay Guitars last page and has the Kay tremelo system. It has a lovely mahogany body.
