I would love to see the spectral response curve of that film.

It should be very close to Tech Pan. It is the film that TP was derived from. Both have extended red sensitivity for picking up the hydrogen line and terrific dynamic range. I imagine the father to both was something the government ordered for photographing atom bomb tests - the atomic test program was also the source of POTA, the basis for Technidol.
