I have around 400 of these in stock. I replace them on every dmd power supply i do.
9 times out of 10 they will only have a value of .005 due to there age and what they are used for.
I know ceramics are not supposed  to loose their value but i always test all caps when i replace them just to see what their value was.
quite often I find that these caps have a chunk blown out of them.

FYI i have found %95 of all caps from pinball boards built in the 70's and early 80's are still close to their original value, but from mid 80's onwards is a different story.

so if any one needs 3 or 4 of these let me know.
