Well two issues here.
First you need to be sure there’s no mercury not in relays or mercury tin zinc capacitors.
A/B/C need work to be anything more than junk.
A/b. Nothing but shred as is. Or a break down of some sort.
A remove all the components and bag the pile together. You’ll probably get peripheral rate for the bag. There’s a measurable level of nickel and silver.
B is a power supply. There’s not much to it. If it works sell it on mercari or ebay. If not it’s just a power supply.
C oh. I hate hate hate situations like this. Pop the plastic top. (Look carefully for the plastic tabs). If the switches and contacts are bold and noticeable take it apart. There is at least one switch in these. Often two. If you can’t find it quickly or see something that looks like a canister capacitor in the middle of the unit put the plastic back on and send it to hazmat. That’s a charged mercury switch. Works like a mercury battery, for ease of explanation.
Otherwise let’s continue
We have one or two silver switches. The switch arms will likely be brass but sometimes gold or gold plate. A large copper coil. The tiny base board will be midgrade from the nickel. Some other random components.
D/E/F are gold finger cards if no mercury.
