D&RGW #50

G'day everyone,

This is my first post here so i hope its not repeating the same topic previously discussed.

I'm trying to locate a couple of basic plans/dimensions for the Davenport switcher, #50. I would be more than happy to pay for a plan or if someone knows where i can buy a plan or at least have access to get a couple of key dimensions. I'm looking at doing this as a simple scratchbuilding project in HOn3. I have access to mechanism components. The dimensions i really need to get started are wheelbase, wheel diameter and overall length, width and height.

If anyone can assist it would be very much appreciated.

Many thanks, J.
