As far i can make out, these appear to be the only previously connected terminals on the fourth image.

Hydovac , you probably deciphered this by now, but anyways, my curiosity
was piqued. Found quite a few useful links which I thought will collate here
for future reference -

I had the same problem with a set of new 25K Mono attenuators I purchased from Super-market8 on eBay.
I couldn’t find documentation anywhere in any of their listings even though I thought there was an illustration posted when I first bought them several years ago.
I wanted to use them recently and also saw the images posted above, but they seemed to be different enough to make me scratch my head and I gave up out of frustration and used some pots I had on hand instead.
I recently sent the seller a message. I’ll post up if I receive anything back.
Pic of my version below.

Different types here: 1st pc it's a series & 2n pic it's a shunt.
Series is summing the resistor value of each step: for example if you are using step 6 you have the total value of 6 resistors. Input is the first resistor & last resistor output is ground, so source sees always the total impedance of all 23 resistors if the stepped attenuator have these steps.
Shunt is only one resistor each step, so the source doesn't see always the same impedance.
