Welcome to the forum and when you get a chance go to the intro section and start a thread there.
Most important in my mind is that you have permission from a person who can give you permission to take this material home.
In the end everything depends on what your buyer has to say. You can take them to a scrap yard and see what you can get. You could melt them and remove the much of the stuff other than the CU. I warn you its unlikely worth the effort.
I also think that if there were significant amounts your company would already have way to recover and sell this material.
BTW we like photos 73, Mike
