About this model

Here are files for BR Class 120 DMU cabs, underframes and seats. They are drawn full size so scale to suit your model. I have had requests to publish these, so here they are. These have been drawn for a while but not published as this was for my personal use with brass etched coach sides and underframes from a kind friend. They are also suitable for conversions and scratchbuilds but please note the Swindon Hawksworth windows were not quite the same as the BR MK 1 sides. (But not so as you'd notice in 4mm once it's gone round the layout a few times ;) ...) Anyway, Enjoy Jonny
