Seen beside road

Saw this beside the road just east of Tucumcari, NM yesterday. Anybody
have an idea what this is, other than the obvious, ie.. a homebuilt.

Is this a one off or plans built, or what? Anybody seen this design
anywhere?

I stopped and called the number on the for sale sign (asking $5,500) and
the present owner has no knowledge of builder (now dead) or design name.
Is reputed to have flown only once. No flight damage, just a bad case
of neglect.

Thanks for your help.
