Unknown (LP DC)

While searching for Harmony guitars, I found this dual P-90 "Les Paul Double Cutaway" style guitar from some unknown time period. It's incredibly odd because it's got 2 Dog Ear P-90 style pickups in it, which no other Harmony model I know of to date has P-90's in it. It is a possible Samick build but what I can tell from the images, it looks more like a Yako or some other plant where the H80T and H804 were built at, as well as the hardware suggests that time period.
