Looks like some kind of steam walker, but it’s actually one of the Stirling engines from the Bohm range – the HB14, in fact. Mr Beaty discovered the lot of them when browsing the Mamod Steam Engine website (as you do) and was gripped with a need to possess these beautiful little machines. Whether or not he was able to restrain himself, is currently unknown, but I can certainly empathise. They’re beautiful little works of mechanical precision, able to demonstrate that while steam will get the job done in double quick time – heating air can get the job done too, just a little slower.
