I notice that C&L components are 7mm scale and 31.5mm gauge. 31.5mm calculates to 1.24" in finescale O gauge. But what does 7mm refer to? |

But what does 7mm refer to?Hi Nicholas, "7mm" means 7mm/ft, the scale used in the UK for 0 scale modelling (1:43.5 ratio). One foot on the prototype scales to 7mm on the model. 0 scale in the USA is 6.35mm/ft ( 1/4" / ft ), or 1:48 ratio. One foot on the prototype scales to 1/4" on the model. regards, Martin. |
