I am looking for the dimensions for the original GNR Stirling Single 4-2-2. I'm wanting to build a 7 1/2 gauge at a scale of 2.5/12 in stead of 1/8th, which is the scaling I believe the model companies have followed. I have yet to be able to find the track gauge or width of the original. This preliminary build will lead to a 5/12 I hope in the future. Which I believe will be the 1st 15" gauge build of this model.
Thank you for any assistance you can give in this endevour,
Ronald
