Had a chance to take a better look at your cleaned up pics and it is looking like you're dealing with a bass leg similar to that found in this later model (figure the single 80?F cap stands in for the parallel 40?Fs):?/g/DahlquistSpeakers/wiki/23611
There should be more short pieces of wire on the back of the boards that will fill in the missing pieces of what's connected to what.
Meanwhile, you should probably plan on ordering two or three resistors with your capacitor order. That 4? in the middle should be 5.5? to reflect the later improvements and the single, presumably 4? in the top right will need a buddy to go with it or two to replace it if it's not 4?.
