Smallest quality Traction engine available
 

Hello, What is the smallest quality Traction engine available anyone know if there is.

Small traction engine
 

See www.berrybrooksteam.co.uk and look at the 1" scale Burrell which is gas fired or for something with more detail a 1" scale Fowler class BB1 ploughing engine which is coal fired. Are these small enough?
