Google "Auction number 164639221826".  Click on the link " Norman Laboratories Amplifier". This is the amp wturkey is asking about

Yes. Norman Laboratories, to my knowledge and research, produced no amplifiers. It was suggested that this may be a Musical Design unit. They have been contacted with photos. Eagerly awaiting a response.  

So it was auctioned on EBay? Why didn't OP say "I bought it on EBay, here is the auction number". That is the weirdest thing, to be able to put in an auction number and find out what's going on an EBay. 
That is a serious search engine..

I'm glad OP didn't get an old surplus, Minuteman Missile, nuke still intact... "Clean up on isle 13" for sure.. What's that button do? :-)

Big hole left in downtown anywhere.. LOL Nice cloud, mushroom, right?
I'll never forget "do not look directly into the blast sight", may cause a sunburn..

Regards

I did get an old nuke gyroscope end bearing off eBay, once.

I bought it as it was made from machined beryllium, and no one knew what it was.

As OP suggested, Norman Laboratories appears to only have produced speakers. From what I could find, it's a company that was based in Norman OK in the 70's and 80's and apparently sold in a fairly localized area that included Little Rock AK. Sounds like they were considered audiophile grade speakers for their time.
