Picked these up for $50.

They appear to be the original design cabinets, shorter and wider than the other set I have.

I'm not sure if these crossovers follow the original design, or if they were made by the original assembler, but the guy I bought them from had the towers sitting upside down, and the terminal cups are upside down, so I'm not entirely sure how the woofers have been wired...

You can remove the two Thermistors ( ?? better: NPC ) if you feel not to crank up the volume too much in order to destroy tweeter's voice coil. The 100 nF caps paralleled seems to be a ( questionable) upgrade, you can remove 'em too.
A film cap with 250 VL would be the perfect fit for the tweeter section.
Trace down the circuit on paper then everything will appear in the right perspective.
Your question about the woofers being upside down makes me think that you think that this system is 2.5 way where the 2nd woofer has an additional coil for extra lowpass and should positioned near the floor, eh ? IDK !
