network N1200 . Ohio seemed to be a hot-bed for '60s JBL stuff. That's probably a C40 cabinet with the 001 system which includes the N1200 crossover, LE175DLH mid/high horn, and 130A woofer. A picture of the crossover would help to date the system. The newer ones are black, the older gray.

Hard to say and the pictures aren't that clear. I can't even be sure if that's an 075 UHF ring-radiator from the photo but I suspect it is, which should make the other crossover an N7000. Just judging by the screws used for the N7000, one might suspect that the 075 was a later addition which wasn't uncommon, but as for home-built, some more and better photos would be necessary such as something that shows the interior and the labels you mention showing the cabinet model number. It would also appear yours has the aluminum legs. Do you have just one cabinet or two? And what are you trying to learn? Is your interest purely academic and you intend to keep them, or are you searching for marketing information?

A set of eight good aluminum legs can bring over $300 by themselves. If your cabs have the 075s those can bring several hundred a pair, too. Same for the N7000 crossovers. If you were to sell, I'd sell the legs as one lot, go to Lowes and get some short wooden legs like JBL used, too, and fit those and sell the system complete with wooden legs. If the wood veneer is perfect (yours looks darker than most but they were available in several finishes) and the pair matches, they might bring $1000 or so these days. Normally in average condition that pair is a sub-$1000 pair. But they're nice if you want to keep them, too. They're just not the kind of JBL that brings the big bucks (thou$ands) on Ebay. Others will have different opinions, for sure.
