Gottlieb relay return springs

Old-style Gottlieb magnet relays use spring A-4965; the newer AG relays with a plastic armature plate use A-5081. On old-style interlock relays, A-4965 goes on the coil whose armature carries the switch stack and A-574 on the other coil. New-style interlock relays use A-5081 on the plastic-armature relay and A-574 on the other.
