These five dwarf signals are new old stock in their unopened original packaging. I am not sure of their age but as there are no bar codes I'm guessing that they date from around the 1970s. According to the envelope my Dad bought them in 2014 but didn't get around to installing them. Walthers Beejay signal kits, U752 1 indication dwarf signals, complete with 12v bulbs. Full instructions are included. Due to their age I cannot guarantee that they work as I have been unable to test them. Please see photos.
