Help identifying this x-ray machine I found!

[breezetix]

I found three x'ray machines a little over a year ago at a scrap yard. Few months ago I went to the yard again and they are still there. Asked my dad if we could go take one or so and bring them home, and he kind of agreed. One or two of them is an AMX 4, did a bit of research and the x-ray transformer is rated for 125kV at 100mA constant, 320mA intermittent. Battery powered so I assume it has IGBTs in it, and drives the xrt at a few kHz, which is perfect for me. But I need help identifying this machine in the start, so I could do a bit of research on it (if any at all). Thanks! All I could find was "GE Medical Systems" or something on the box, and that's about it.

I once found a AMX 2 from 1979, it was also a battery supplied unit, based on SCRs. So not really useful for anything.
