Tryin' to identify a 4x12 cab

I just picked up a 4x12 cab at music-go-round and I think the sales guy was upset. They didn't know what brand of cab they had and were just advertising it as a no-name 4x12 for $199. It looks like the late 80s, early 90s 4x12 Mesa with that thick metal grating, but it's not a half-back, it's sealed in back. Also, the grate looks like it's missing the emblem, "Mesa/Boogie." So, I asked if we could pull the grate off and look on the back of one speaker, just so I would kinda' know what I was about to buy. When we did that, we identified the speakers as Celestion G12T-85s. Needless to say, I bought the cab. But, I don't know if Boogie ever used such speakers. I think I may have an old Rivera cab, but I'm not sure. It sounds freakin' awesome with my blue voodoo 120. Anybody got any thoughts on who may have originally made this cab? Thanks.
