Yes, that's what I think.

A while back I designed a trailer for ASK21 (which we didn't build,
that's a different story), in the process of which I obtained the
drawing set that the factory supplies so you can design trailers and
fittings and such. When I overlay that ASK21 fuselage side view on the
Acabion, and use perspective tweaks to approximate the plane of
symmetry, it matches to my satisfaction.

The one thing that differs substantially is that on the ASK21 the aft
canopy rail curve is kinked a bit to clear the wing, and that feature
is absent from the Acabion. That implies that they've reworked the aft
canopy rails a bit. They're probably using stock Mecaplex ASK21
acrylic transparencies, though, since the raw transparencies probably
have enough extra material at the edge to let them fill in that kink
without needing to develop a whole new transparency forming plug.

Thanks, Bob K.
