Rare Petrol Oil hand pump oil can veteran car motorcycle vintage brass tin. Really unusual twin chamber brass oil / petrol pumper can. Been nickel/ silver plated years ago but that's partly worn away.
Feels very very well made, turn the little knob on the neck to change from the petrol chamber to the oil chamber. Very unusual, would've been the bees knees back then! It's had previous solder repairs but it seems to work and hold liquid find now.
