what kind of power plug does it have on the input? If it’s a North American plug it’s 120v in. It looks like a NA jack on the output so it most likely is an isolation transformer but before you use it plug it in the wall and measure the output voltage with a meter. It should be around the same as the input voltage, like 120 or so. if all is good there try plugging in a lamp first. If that’s ok go for the amp with a good fuse in it. Make sure it doesn’t get too hot. Too hot means you can’t touch it for more than a few seconds. Do all this with someone else around just in case!
Make sure they are isolation transformers rather than autotransformers. Sometimes they do that to convert between 120 and 240.
If they are autotransformers, you might still have a useful donor core for a custom rewind. You wont find laminations like those anywhere for sale for $4.50.

I’m picking them up tomorrow and will post better pix. I’m getting all the stuff in those first pix plus a chassis I might be able to make a down and dirty OTL with.
Is that an standard AC socket on the side? If so and there’s a standard ACplug on the cords on each xformer, they are probably isolation transformers.
Yep, standard in and out. No other marking so I do I tell how many amps it can handle if I plug it into 110v and measure 110v out?
