Here's a weird one:
This is a picture of a Cameron-Miller 255, an electrosurgical generator. It is used for different kinds of surgery, including cutting and cauterization. It accomplishes this by heating up the tissue between the electrodes with current, in the range of 0-100 watts. It's pretty easy to tell that this was made a while back because it is constructed from more modern ones, but the label was removed and a quick search reveals no results.
There might be some useful parts inside which could be reused, but I think it is best left off until someone figures out a use for it. Any ideas?
