Red Double-Decker Bus Model

Charming red double-decker bus model with Royal Botanical Gardens banner. Perfect for collectors. It's a piggy bank, that has lost the plug in the bottom. The top comes off, I cant imagine why, but it was clearly made that way. Purchased in the 70's or 80's. This has been in our family since it was bought. Made of metal (cast aluminum?) it has some weight to it.
