[R-390] C553 ever a brown beauty?

While I fully agree with the recommendation, did they ever manufacture
IF decks with C553 a brown beauty?  I've always seen Sprague Vitamin Q's
or Westcaps in this position in apparently original IF decks.

It's possilble that the depots swapped out brown beauties and put in
the metal-can-with-hermetic-seal caps decades ago, of course.  My
experience is definitely not with pristine all-original radios.
