Okay, Snade's pic of the crossover definitely cleared up what's going on with your xover, Johnny. The left-most connector of the right-hand pot is the one. (In the 1971 schematic this is the connection between the upper "32 ohm pot" to just above the lower coil, marked "101 (1.0 mh?)"
Those are definitely interesting CTS woofers. The alnico magnet seems like it should be an earlier version, but the date is 1973, and the surrounds are very strange. Instead of the normal treated coil surrounds, it looks like they took regular foam surrounds, inverted them, and treated them with something. The version being sold on ebay looks like identical except it has regular old foam surrounds and they aren't inverted. I assume the treated surrounds are intact?
Perhaps yours was an even later version with slightly different woofers. Interesting that they mounted them to the front, which would theoretically have a bit better phase coherence (although neither are all that great) and less diffraction, as I understand it.
I also want to repeat that I HIGHLY recommend recapping those crossovers to get the most out of those great peerless tweeters. Saintjohnny and Snade, looks like you've got the 60uF and 2uF version; and Njord, looks like you've got the 100uF and 2uF version. I used solens for the larger values, and splurged for film caps for the tweeters.
