Diagatubes were standard on the largest two sizes, 58 and 62 cm.
Parallel double top tubes were never standard. They did exist on several
prototypes, because parallel double top tube was almost the design. But late in
the design process, Riv changed it to diagatube before officially releasing the
bike.
Bombadils of the era (which predated Hunqapillar by a bit) did come standard
with parallel double top tube. But eventually those too switched to diagatube
as well (and included diagonal tubes in the rear triangle as well.)
