I'd bet my granny that that is a modified / cut down MKI Tranny back end dropped onto the VW floor-pan........ The swage lines along the side leading to vertical taillights (indicator over reflector over tail-brake). The side hinged opening outward swing door (clearly left hooker) is also classic tranny shape - modded with a panel with window let in...
Post some more photos around it (back, other side, interior...)
Certainly seems a well built homebuilt........but very, very doubtful that it is a Hobby.
(Better let me granny know that she may be moving families!!!!!!!)
it's the roof curve/line and metal pressings for windows dont look like a tranny, the actual sides do as does the hinged door, the rear lights are vw units
the other pics i have are tiny, i'll get some more when i pick it up next week
