I dunno, just felt like doing that. I've found that you can make a K7000 work with most tubes, if they're 25" they're all very similar. Your first one was more likely once a Hantarex Polo monitor! Pop a isolation transformer and a K7000 board in there and call it a day. The second one a K7000 will work in too, I'll bet.
BTW, take a picture of the PAN of the second one. I can see the pan of the first, it's obviously for a Hantarex, as well as the yoke connectors. The second one I'm going to guess was maybe a U2000.
Upon further reflection, I don't know if you can stretch a K7000 33"... so that may not work out for you. Hmmm.
