Does any know what brand this is?

I have had this for ten or so years. There are no identifying markers of any sort. I thought maybe it might be an old Supro, but that is just a guess. Please let me know if you know!
Thanks ☺

Good guess, since probably there was a lot of post WWII cross-pollination among the Chicago makers of Harmony, Kay, Regal, and National/Supro/Valco, with Gibson maybe tossing an occasional body into the mix. The three-bolt neck to me suggests Harmony, but that headstock is Kay all the way. This being said, your Kay I doubt is a Chicago Kay, but a post-1968 early Japa-Kay. A few eBay searches should give you some insights.

I don't know, but that is cool-ass.
