There is no real standard so you will have to guess. Or, heretical me, measure it.
If you don't have a measuring device, get one, or make one. Simple to do.

Thanks, I still need to get an old condenser tester, heathkit I think I was told was good.
I would also like to get a smaller digital tester.
So I guess I have got all these disc caps figured out now
thanks to everyones help-
For the 270K N750,
I'll just get a 27pf silver mica.
The 47k, I'll get a 47pf silver mica,
and i'm just not sure of the 470 disc,
since it looks just like the .0022, and .0047 UF discs.
I'll order both UF and PF and figure it out when I get the tester.
Thanks again for the help!!
From now on, I will know how to check!
