However, in connection with something that I'm designing for 5522, I've been poring over a number of detailed LNWR wagon diagrams. These seem to be consistent in showing:
Buffer height 3' 5 1/2" or 13.83 mm in 4mm scale
Is that loaded or empty?
Underneath of wagon/van floor 3' 10 1/2" or or 15.50 mm in 4mm scale
Except that models of wooden framed wagons are not constructed the same way as the real thing. On the prototype the floor planks sit on top of the solebars and there is a covering board bolted to the outside of the solebars that covers the ends of the floor planks. On most models the bottom of the floor is made level with the bottom of the covering board and the solebars are stuck onto the bottom of the floor. So the height to the bottom of the floor is going to be less than that on the prototype.
