Anyone know how to identify the source of this JBL N800 crossover?

Ok... as usual this thing ate my post... lol...
Just found this cool, very old JBL N800... typically made with the altec name...
Saw some stuff on line that these may have been used in the giant Ampex monsters they made for theaters in the 60's... not sure but were they in the 50's???
The JBL label looks ancient on these... just curious if anyone knows about these. Specifics. thanks!

Those Jim Lancing stickers are from the 50's. Not Altec's
If you have a pair they could be used for a resto project.
If only a single/ good luck finding a match

Exactly. As best as I can tell, they were used in the huge AMPEX enclosures that they were in stalling in theaters... those were the only ones needing anything this size! And I recognized the age right away... it wasn't until I searched for a while that I realized it was a 50's era... and the serial number is 102 !!! That means it's likely from the first pair they made!! Most serial numbers start at 100 or 1000... etc. Beings I don't see finding the mate... and that those are supremely collectible, I foresee selling them to a collector. That way I can get stuff I need! lol
