do old diesel generators have copper inside?

i got a big yellow diesel generator on a trailer it doesn't say what brand. It probably weighs between 2000-2500 I'm guessing. I just dont see a copper motor anywhere on it any ideas??

Do you have a picture of it? Does it have a data plate with the KW on it?

its a atlas copco thats been sitting for years its really old i think its 25 kw ill try to post some pics tomorrow if I dont scrap it.

I junked out a welder last year and there was hardly any copper inside it; mostly aluminum windings.

If you could get the diesel running, you would make more money. There's a pretty good demain for 25KW diesel generators.
