Please help identify a capacitor

[jpyerry]

I really hate to post a newbie question, but I need help identifying a capacitor. I have attached a photograph containing two capacitors, I am almost certain they are mica capacitors. I have searched for how to read the codes on the capacitors and I just cannot seem to figure out what they mean. I also tried measuring the capacitance with my multimeter to try to narrow down the possibilities to give me a clue as to how to read the values, unfortunately my meter gives me wildly inconsistent numbers every time I try to test the capacitance, so no help there.

If anybody can tell me how to read the codes on these, it would be greatly appreciated.

Thank you very much.

The look like cornell dubilier mica capacitors 20pf/100v and 50pf2%/300v
You need a capacitor meter to read the capacity.

I appreciate your help.

So, the ".7" after the twenty doesn't mean anything? I wasn't sure if it was a multiplier or some sort of tolerance specification I wasn't aware as this is the first time I have actually seen mica capacitors and it was really throwing me off.

Never mind
