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?
