Harmony Jumbo Black Acoustic in Bentonville AK for $69

I cannot seem to identify this model Harmony Acoustic the seller is offering. It has a jumbo shape like a Sovereign but is not a 1204 or 6364 (or even a Black 162). It has the 50's-60's Harmony logo and Treble Clef and "Steel reinforced neck" but no Made in USA stamp. To make things more confusing it has what appears to be one of the wooden tailpieces Harmony only used from 1941 through 1945 and it also has a Zero Fret (WTF!??). Is this an Asian reissue?

I am totally confused. I suppose this could be a "mongrel" (i.e. a non-stock guitar from various model parts) but if anyone can help identify it please let us know. - JC
