I bought some new 110pF caps that are marked like this: (3rd line down)

Cornell Dubilier
Mil-C-5
CM05FD111FO3.........THIS IS ON THE CAP
110pF 1% 500Volts
Radial Leads
Dipped Mica Capacitors

So what on the cap tells me it's 110pF?

Here is the code, go to the data sheet.

The "111", meaning "11" times 10 to the "1" power, that is 11 * 10, which reduces to 110. Just like the resistor color code, except with numbers.

Thanks to all. I think that I'll carefully write 110 on the backs with permanent marker .

I recommend learning to interpret the code. This isn't going to be the last coded cap you'll see.
