Two from Steve Hall.
One is Hornby, straight out of the box, just re-wheeled with Alan Gibson P4 conversion wheels/3mm axles and screw link couplings fitted. The chassis , motor and valve gear are pure Hornby and is a rigid chassis apart from the rear axle which is sprung. Time spent on conversion = 25 hours.
The other is built from a Brassmasters Kit, Ultrascale wheels, Portescap motor. Loco is fully sprung, tender is compensated and it runs like a sewing machine. Total time to build and paint = 200+ hours
Question is, can you tell which one is which?
