Lot 0034
Very nice original non-return valve from World War 2. This valve was commonly used on the Mark V diving helmet. This valve was made by Schrader and does feature a US Navy inspection stamp. This stamp shows the part was inspected and put into US Navy inventory during WWII. If your Mark V or vintage Schrader helmet is missing a non-return valve - this is a perfect example to make your helmet complete!
