I guess (purely out of interest) one way to find out whether they are mica or not is to measure them. It might be a bit tricky with a regular meter as it will show about 100pF when not connected so it needs too be zeroed first; if it shows close to the nominal value, it is then a mica; if it shows a different value (paper caps migrate as fas as 2x to more the value) then it is paper.
Has to measured out of circuit, with the wires around clipped.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
