An unusual one this is a tried and tested  fully working  replica of the 1929 Mecanno  vertical steam engine  mounted on a wooden base and fired by  a Bix gas burner  with their small gas tank.  Very powerfull for its size  ! Base is aprox 29CM X10 CM Overall height to top of chimney Aprox 20CM .   Manufactured  by Tyco about whom i know nothing ! I would be gratefull for any further information .
