Silent Watchman Corp Electrical Deadbolt Heavy Duty Lock With Keys. This item has been moved around so there are some scratches bumps and bruises there's a little bit of rust in one of the corners please look closely at pictures it is in great collectible condition normal wear for this item and its age.. Comes with five keys and wiring.. I have not tested it electrically so i do not know if it is working but the keys do open and close the deadbolt.. From the way the keys look this is probably from the 70s.
