What can replace .005mF waxed paper capacitors from 1949?

I wish to revive an RCA radio from 1949 that contains a number of waxed paper capacitors. I have found film capacitors on the Digikey site for all but one value - .005mF. Inside this radio are five of them but of different voltages. One is 200 volts, two are 500 volts and two are 600 volts.

Any suggestions on what to use for substitutes? If there are .005mF capacitors still available, and are 600 volts, that should cover all of them.
