I believe this is a rare version with the dual can - having the oil can compartment, sadly the cap for this is missing but the main can has a Shell brass cap on. The Shell clam logo is pressed in the front and back with older paintwork. Looks like the bottom has 12 and 31 on it - so I believe this is produced in 1931? It is empty and I have not put any liquid in it so would not advise trying to use it.The item "1931 Shell Gallon Petrol Can Dual Motor Spirit & Shell Motor Oil Duo Can" is in sale since Saturday, October 3, 2020.
