I did a quick search of the site but found very little on radial

Were the Central Valley radial roofs (from the CV stockcar)
specific to
the NP or could it be used on other roads' cars?




The CV roof represents the NP's unique "circular" outside metal roof,
which (AFAIK) was not used by any other RR.

Did other manufacturers of radial roofs use a more prominent seam
cap on their
roofs?



Yes, and on the Hutchins, Viking, and Murphy radial roofs the curve
or arch of the roof was shallower. Also, both the Hutchins and
Murphy roofs had small intermediate stiffening ribs in each panel,
and the Viking roof had two such stiffening ribs in each panel.
