DUNLOP MK III VALVE - 27VA/4931 - AC 12708 - OVERHAULED

Here we have a boxed original Dunlop MKIII Valve for vintage aircraft. This item is still sealed.

The box shows the following.

RAF Section Reference - 27VA/4931

Dunlop Part Number - AC 12708

There is the letter R in a circle on the box which I assume is to signify reconditioned by Dunlop.

A nice warbird part.  No airworthiness is implied
