Has anyone seen the little toy steam boat with a flat pan boiler?

Question

It is about 7" long and has two tiny pipes leading from the boiler to the rear.The top of the flat boiler has a very very thin metal foil so when u fill the thing with water and put a candle under neath the foil pops up and down and the toy moves along at a cracking pace.
