This is an early Poole chassis model fitted with gaugemaster dcc92 decoder and marwick brush. The model has a brass drive gear and surprisingly copper pickups which look like they have been a replacement for the original silver ones as the lower plate retention screw is cosmetic, there is no chassis screw hole in which to insert it so it has been cut short at some point. It runs remarkably well on dcc as can be seen here https://youtu.be/-gGwGoswxpE
Does anyone know the exact vintage
Older Graham Farish model with brass drive gear circa 1979. This was a repair followed by dcc conversion, runs pretty well which can be seen in this video
