Just picked up a vintage Airguide compass for my truck and I'm trying to get the light to work. The compass supposedly takes an AAA battery. The problem I'm having is that the AAA battery won't slide into the end cap. The original instructions call for a Burgess #7 or Eveready #912 battery. These batteries were zinc carbon type batteries. Is it possible that the Burgess #7 or Eveready #912 were a smaller diameter that the modern day AAA alkaline batteries? This compass also says it requires a 1.1V .22 Amp penlight bulb. The only replacement bulbs I can find are 2.33-2.5V penlight bulbs that require 1.5V batteries to operate. Anyone know where I might find the low voltage penlight bulbs? Any help would be GREATLY appreciated!
