WW2 Grumman TBF Avenger Altitude Limit Switch SA-1A/ARN-1 110FB/386 50-300 Feet 

This vintage aircraft gauge is a WW2 Grumman TBF Avenger Altitude Limit Switch SA-1A/ARN-1 110FB/386 50-300 Feet. This type of switch was quite commonly used in aircraft that needed to maintain a steady altitude during low level flying and attack.

In fairly reasonable condition, the gauge is missing a knob and has surface blemishes, including a dent on the top of the gauge and a small chip in the glass face cover.  It was made in the US and has not been tested.

Approximate Size:

• Face Diameter: 7.5 cm / 3"
  
• Depth: 13.5cm

The Grumman TBF/TBM Avenger was used by both the US Navy and the British Fleet Air Arm as a torpedo bomber.

A nice aviation collectible or piece of steampunk!
