[cctalk] Might be antique computer parts

I have two SPST time delay 12-volt relays packaged like vacuum tubes with octal bases, Amperite models 12N010 (ten seconds) and 12C5 (five seconds). They're in their original boxes. I have no idea what devices used them. It seems a shame to throw them in a recycle bin. Does anybody want them? Van Snyder
