Preowned O Gauge 45XX Part Made Springside 45xx Kit

A part-made O Gauge GWR 45xx 'Prairie' Tank Locomotive Kit, white-metal body and brass chassis both part-made but unpainted, motor fitted but axle gear loose in box, together with many other small parts, 

The kit looks complete but has not been checked!
Wheels are a little rusty and need cleaning and it will require Pickups
