Help reading capacitor code values

[blue]

Hi,
I have a bunch of silver (colour), axial lead capacitors. They are about the
size of a 1/4 - 1/2 W carbon resistor. I don't understand how to read the
capacitor values from the markings on them, and webpages I've looked up
don't help too much. I don't have a meter that reads capacitance, and I
don't really want to make mistakes with the values. Hoping you can help me
to understand how to read these. Here are some examples.
Thank you in advance for any help you can offer.

....
These are all mil specs. The only way to get the value from this number
is to have a friend in the Gov't procurement office look up the spec.

Or be in the military and look it up yourself. ;-)

The other option, of course, is a C meter.

Good Luck!

--example1--
39003 <-- Mil spec number
01-M <-- spec sheet number and trademark
2283 <-- Military dash number and J for JAN
+419A <-- polarity marking, Date code, and lot symbol
-------------

Ex 1 is a 2.2uF, 20V (at 85C or below) axial leaded tant cap. + marks polarity.

--example2--
39003
01-M
2267 J
+524A
-------------

Ex 2 is a 2.7uF, 15V (at 85C or below) axial leaded tant cap. + marks polarity.

--example3--
39003
01-M
2283 J
+545A
-------------

Ex 3 is a 2.2uF, 20V (at 85C or below) axial leaded tant cap. + marks polarity.

--example4--
M39003
01-
2408J
31433 <-- on "B" case, this is source code
+737 Y
--(there is a crown mark between the 7 and the Y on this one-----------

Ex 4 is a 2.7uF, 75V (at 85C or below) axial leaded tant cap. + marks polarity.

--example5--
M39003
01-2
2362J
56289+
8850F+
----------

Ex 5 is a 2.2uF, 50V (at 85C or below) axial leaded tant cap. + marks polarity.
