The GNR Howlden flat roof coach project

A small update but now I've made a new chassis for de Dia. 156 composite (the one that I have used to test out the new interiors). Previously I had been using the chassis made for the Dia. 301 full brake and Dia 245 5 comp. third for it, but the length of the full brake and the third come in at a scale 32' while the composite comes in at 32' 10". In 4mm scale the 10" become 3mm.I thought that wasn't relevant until I actually leghthend the chassis by 3mm when I saw just how big of a difference it made!
