WWII Bomb overflow tanks

This U.S. WWII AN-M30 100LB Bomb shaped coolant recovery tank may be mounted next to the radiator or on the firewall.  It is

• made of copper and brass
• 3" diameter
• 15" in length
• two studs for mounting to firewall or fan shroud*
• holds ~2 pints
• GP - 100LB AN-M30A1 stencil in black
• Kilroy was here stencil in flat white 
  
• Made in the USA

*please advise if you intend to suspend or mount horizontally

Should the system pressure exceed the cap’s rating, the spring will compress and fluid will flow through the shorter tube to fill the chamber.  

In the event the recovery tank reaches capacity, the fluid will find the second longer tube and exit to the street.  A vacuum will draw the coolant back into the cooling system as the engine cools down.
