Good Morning, Better Sense,
It has to be old stuff, but, given its low speed, it may still be good, especially if it spent the last several decades frozen. It is an extremely fine-grained film which produced excellent-quality copies of old B&W prints. My Kodak data sheet from 1971rates it at E. I. 64 under tungsten and suggests developing in D-19 for 6 minutes. I'll be glad to copy the complete data sheet and send it if you want.
One thing I used HCC for some years ago was to make positive transparencies from negatives, both B&W and color. I can't remember typical exposures, but I do recall processing some of the film in D-19 and some in Dektol 1:1, probably for times similar to that cited above. I think I still have a couple of cassettes of HCC somewhere in the freezer and would be interested to know what kind of results you get.
I've never tried it, but I suspect that you may be able to get negatives of non-copy subjects by processing in Technidol or some similar extremely soft-working developer just as with Technical Pan film.
Konical
