I realize this is several years late.....but here goes:
CP05A1 is an insert tab wound kraft paper aluminum or tin foil depending on the size of the part. Its possibly impregnated with one of three materials.
CP11 is similar to the CP05 above, just has a different physical configuration
CQR39A1 - I really need the next letter to tell exactly what it is - that letter is the characteristic code
Hope this helps someone

West-cap info
I will let everyone in on a secret - most of these old military caps, the information can be found here

It requires a little digging, but the entire specifications can be found there. Now that does not necessarily give you the design details, but gives a ton of other information
Regarding the CQR39A1K....charcteristic "K" is typically for Kraft Paper & Polyester film, which is impregnated with something. Not all mfg'rs use the same snake oil. These should be a really good audio grade capacitor.
Cheers
