The first place I'd go for something like this is Antique Electronic 
Supply (Note: they're local for me, but I have no connection):

Since their website uses frames I can't give a direct link, but if you 
navigate Capacitors->Multi-Section->FP (Twist-Lock Can) you'll find a 
lot of stuff similar to what you've described. Mallory spec, made on 
original Mallory equipment.

CE Manufacturing seems to be the source of a lot of this stuff, but 
they're just AES under another name...

Unfortunately they don't have the exact combination you're looking for.

Tube World has a lot of stuff too:

Nothing exact, but some that come close and might work. Pretty 
inexpensive too.
