another what the heck are these thread.

I think the black thing you are holding in the third photo is called a "selenium rectifier". They used to use them for converting AC to DC back in the age of tubes and early electronics. I used to see them on old motorcycles, too. Probably not much scrap value.

The flat stainless device with the name "Siemens" on it is likely another type of bridge rectifier since it has 4 terminals and two show a kind of universal AC symbol "~" and the other two show a "+" and "-".



I think Mech has it nailed...if the old transistor has any gold on it, it's probably the only item worth anything in the lot.

Now that I think about it, the Siemens part came out of a rectifier , now the question is, was it worth removing, or does it go in the shred pile...
