Sometimes I just cannot resist an unusual piece of junk from a ham radio swap meet. Look closely & you will see two J-38 Morse keys stuck together sideways, to make a dual-lever paddle or a cootie key. Don't know which, because it actually doesn't work at all right now. I plugged it into the rig for fun & only got intermittent results on the thumb side.
It's a good paperweight, though. It weighs about 5 pounds.
