Just a comment to the earlier poster who mentioned "1:48 Scale Proportions" on the side of a Rail King loco box. There might be a difference between 1:48 Scale and 1:48 Scale Proportions. If a loco were 10% shorter, 10% narrower and 10% lower in height, but in all other respects a scale model, would it still be "1:48 Scale Proportions"?
