A caution on modelling the insides of brake vans: You need to make sure that you have all the right informatiion before you start to detail them. You can't build eg an AA6 brake van with a AA19 interior as they all had different interiors. Moreover as they were repaired and serviced and had overhauls, they became increasingly different - even each series could vary. I used fior reference GWR Goods Wagons" by Atkins, Beard and Tourrret (pages 473- figure 447 and page 480-figure 649). The paints are from Precision, Humbrol and Revell, while transfers came with the kit and I gave it a coat of Precision matt varnish.
