Given that it's an *302 film, I would presume it's a slow, ordinary emulsion (blue-sensitive only, so you can process in trays under red sagfelight) used for copying purposes or for making large transparencies from negatives.
In 35mm, you can find 2302 (estar base) and 5302 (acetate base), which are usable in movie production for doing positive prints from camera negatives.
I have successfully used 2302 developed in stock Dektol to make B&W positive transparencies from my negatives, and also as an EI 2 or 3 negative film. It's sharp and fine-grained, no doubt about it.
Note that although it says "Positive" this does not mean that it will create a positive image in-camera. It rather means that it is designed to BE a positive. Think of it like graded paper on a transparent base.
But you have to like black fire hydrants...
