This model is very similar to my other 40t armour plate truck, so please read the notes for that one as well. The main difference is that this one doesn't have the planked floor, and so is more like the original build, or the later conversions to concrete beam carriers where all or part of the planking was removed (or maybe never added in the first place). You can of course add a partial or complete floor to this one if you like. Without the planks, the arrangement of longitudinal and transverse beams was largely open to the track - apart from eight chambers which were chain boxes, presumably with a floor at the bottom which is how I have modelled them. The concrete beam carriers had a few different superstructures added and if you want one of these I suggest you make your preferred kind from plasticard and add it to whichever model suits you best. However, if you tell me which photographs and drawings to work from, I'll consider making one for you. The other differences from the model of the planked 40t are a coupler hook plate on the bufferbeam, a tiny bit more clearance for the bogies to turn under the wagon, and a tie bar between the axleguards which can be seen on some, but not all photos. If you buy both models, you could swap the bogies, or if you let me know I'll upload the bogie designs on their own as spares and replacements. Thanks again to Paul Bartlett for making his wonderful photos available on line and free to view; It's amazing how much it helps to have more photos than the one or two you get in reference books, vital though those are for the history and technical drawings. I've also uploaded the 55t version now with floor planks, and I'm thinking of uploading the same without planks. The 55t had 6 longitudinal frame members to the 4 of the 40t version, and some of the various different superstructures added for carrying concrete beams can be seen in photographs to be raised on 6 rather than 4 rails, or 4 but at different widths, depending upon which version of the armour plate truck they have been built. Have fun.
