Office of Steam Forum for Model & Toy Steam Gas & Hot Air Engines

 I saw this one also on e-bay recently, I have seen others but don't have one myself. But surely it is a classic in toy steam history, I did not know that the boiler was made from an otherwise ordinary product, very clever and resourceful! Reminds me of some toy cannons made after WW2 from re-purposed surplus grenade parts (well, sort of!).
