Somebody call?
Looks like a Micro Air New Zealand B22S Bantam, with the rear fuselage enclosure missing:
The bubble canopy, tail skid, and overhead flap lever are particularly distinctive IMHO.
I think that the type was approved in the UK in the mid 1990s, so if that was taken in 1990-92, particularly given it's not in the UK mod state (no rear fuselage enclosure, cables instead of struts on the upper tailplane bracing..., is that a Rotax 503 on there? - compared to the 582 used on the half dozen sold into the UK market) I'd guess that it was a visiting foreign example - maybe on a sales tour?
Interesting photo.
