That vertical looks 100% Desire to me. Plus, it is a plug-in wing design which appears to have no belly pan (except maybe a chin cowl) and a removable canopy to access the interior. What doesn't jive is the nose. I don't think the Desire looks liked that. There's also the fact that I'm not sure a mold of the desire was ever made commercially, only the top deck was made in glass and it didn't quite look like that. It seems to be of that era though - early to mid 80's. Desire, Summit, LA-1, Eclipse, etc.
