I found these in the dump the other day. Laying in the snow with a lot of other "junk". I loaded the van up pretty quick and got out of there.

These seem to be solid aluminum which at the scrapyard would get me probably around $5 if I cleaned them up. Not bad for free. Throw them in the aluminum bucket and get a coffee when you get to town.

But then I looked them up.

Ummmm, I have two of them. Even if I got $50 I would be happy but if I download the manual and figure out how to test them and get them working it would probably be worth my time. Or I can just say they are untested and take my chances. Either way, it will probably be a lot better than the scrap price.
