Going by the shape of the truss cover and the shape of the headstock I suspect it is an early Hondo (guessing anyway), or at least based on a Hondo design. The truss and HS are very close to an older Hondo I had, but I suspect mine was a little newer buy a year or two maybe.

It does share a number of characteristics in common with say the TS series with that laminated body, heel, 3-piece neck, what appears to be a recessed bridge, and the one remaining notched knob.
That truss cover with the arched "Professional" on it looks familiar, but I can't place it. I do have a truss cover nearly identical to it here and the previous ownwer said it came from a Hondo.
