If 'Nihon' is the basis of the company logo, it could be any 
number of companies of Japanese origin. Nihon = Japan.

These older logos are not easy to track.

Your cap logo has an additional " I " vertical.

Doubtful.  The OP's pic has a definite 2 in a circle with an additional '1'
or 'I' vertical outside.

The Nihon Inter Electronics logo is the letters NI with a circle around
them.

Yes an N can look like a sideways 2 if you squint hard enough, but the two
logos are visually quite distinct.

Aha, it's a Sprague Cera-Mite ceramic cap, 0.01uF 3kV d=29/32", t=1/4".
41C121A2 is the 'Sprague OEM part no', and the 'Sprague Products Cat.  No.'
is 30GA-S10.

Page 53, dating from 1963:

Perhaps the 'circled 2' is their mark for an OEM rebrand, or relates to the
OEM they were relabelling it for?

Great! Many thanks! Maybe the reason for using this capacitor instead
of a second standard marked capacitor (like the parallel one) is the
same as using IC's with milled away markings.

Best regards

Maybe, or maybe there was some different T&C for using an OEM marked part. 
eg you got some different level of testing or different terms of supply or
something?
