WW2 Vintage private garage petrol tank and hand pump

This old 4 gallon petrol tank with associated hand pump to 'lift' petrol from below ground tank has been up on the wall of our garage since at least 1945. It may date back long before that as I have photos of the original owner's father wonderful old Buick,which he apparently drove often up from Melbourne, out the front of this garage I think as early as the 1920's - definitely pre 1937  The hand pump is complete but ceased -  probably not used much past early 1950's. But all the bolts were surprisingly easy to undo when I took it all down recently- so assume  restorable. Unfortunatley the garage has been condemned as tilting over, which is the only reason I took it down and started the clean up.
Weighs a good few kgs and have left as much piping as possible on to preserve integrity of original piece -so definitely only suitable for local pick-up.
