Well, perhaps I wasn't clear. The the original owner did some research that indicated that the head is an '82, but I'm not certain the cab is also '82. Sorry if that was implied.
It is technically a 215B, but because of the upgraded SPL speakers, it is more commonly known as a 215SPL. I don't believe the Betas or BHs were offered with SPLs.
I took some additional photos of the back of the head and cabinet, which I'd be glad to email on request. Thanks for the interest...E207
