Wish I could help you with that, but don't know, as they are a couple I haven't cut apart yet. I think there is a lot more variability with the Russian caps than is documented. For example I cut a K40Y apart which is documented to be oil impregnated paper and aluminum foil. When I dissected the case and unrolled the coil, I found the outer 3/4 of the winding was PIO (aluminum foil, oil impregnated paper), the inner 1/4 of the winding there was an obvious splice on the foil, going from aluminum foil to copper foil, and the dielectric changed to some kind of plastic.
I have no idea whether this was some kind of anomaly, a variant, or some characteristic of a factory/date kind of thing. Sometimes I think Russian caps might be "like a box of chocolates, you never know what you get". :-))
