Yes, as one who often crewed for Bruce Tuncks at
that time I can affirm that his system of
extending the rails to the outside of the
trailer worked very well. He did it with the
fuselage dolly tracks also. As I recall it was
still a two-person rig, but the basic idea was
dead simple, cheap and is easily transferable to other types of trailer.
On most Cobra style trailers the wing dollies
are made such that the spars sit slightly below
the edge of the trailer sides. However the
dollies don't have sides, so the wing is free to
rotate on the pin. He seems to have simply
raised the dollies a bit (or perhaps just put
more carpet on) so that the spar is above the
line of the trailer sides. This allows him to
rotate the wing through 90 deg while it is still
inside the trailer. Then he just lifts the spar
off and rotates while carrying it to the fuselage. Very impressive.

If you make the pin removable you don't even need
to lift the wing root straight up. Also putting
the roller on a small stand lets you put the wing
on it at the C of G of the wing. Then you don't
even lift the weight of the wing root. Slightly
more complicated but when you see the way that
bloke throws the glider bits around, he's a big
strong boy and his method may not suit everyone.
I've done this without the roller on the stand.
Just reasonably slippery carpet.
