Evening everyone, I've somehow gotten hooked up to what I think is a Facebook group dealing with 1/20.3 scale. What gauge would that be, G? I know there are several scales in G gauge but I am not familiar with this one. Rick H.
Some scales are related to gauge. So the train scale changes and the track stays the same. But it can get confusing because once you get a scale then you get spin off gauges. As I understand it Fn3 is G scale track for Narrow Gauge trains. https://www.cumberlandmodelengineering.com/WhatIsFScale.html
Or Proto 20.32. It is basically 15mm of model to the foot of prototype. There seem to be several model standards that have "gauges" that use that scale, including G and F. See https://en.wikipedia.org/wiki/List_of_rail_transport_modelling_scale_standards
It is Fn3 scale. It is the scale that is used with G gauge track to represent 3' narrow gauge railroads. G gauge tracks measure out to a 45mm track spacing, by designating that to be a 3 scale feet you get 15mm = 1 scale foot
