Anyone know what peavey cab this is?

I think its a P.A cab. circa lat 80's?

 

The cab is a 388-S. There's a Peavey information sheet on it here. Not sure how old the speaker cab is, but the copyright date on the sheet says 1989. The amp looks like a Peavey Musician amp head from the late 70's-80's, which was similar looking to the Peavey Mark IV (if I remember the model number right). I found a Google link here (you'll need to register) to download a pdf of the manual.
