The Spitfire is notorious for having a few parts that are just difficult to find. This little push button is one of those parts. Used on Mk1s in pairs, one on the lower left side of each fuel gauge, and on other marks with just one fuel gauge individually. This one is in very nice condition and appears fully serviceable.
This is the only one we have.
