Yes.
I have a ton of 273 photos but I don't see any with enough clarity to see the cap. Most have black, a few tan, one or two with red, and of course a totally incorrect blue. LOL I bet @65dartcharger will agree that the black is correct.

He would know. I can't remember when tan caps came in, but I'm pretty sure early to mid sixties were black. Especially on Prestolite distributors, It would be interested to "know".
