BRwagon1_110_3mmFS_14_chassis_12

This is a 3mm:1ft scale 12'wb chassis suitable for wagons 21'6" OHS. It comes with a sprue of spare 3mm:1ft drawbar hooks which will probably be separated into a separate model next time I upload - I just need some right now and this is a cheap way to do it.  
It should fit my BR diagram 1/110 rivetted steel mineral wagon body as an alternative to the kit chassis that can be obtained. It needs some bearing inserts like the brass ones that fit the kit chassis, or my 3D printed ones which are the same shape and size. 3D printed wheels are available, but the "normal" 3mm wheelsets are the same and might run a little nicer (and not need painting).
I have not tried this chassis myself yet, so even though I have offered it for sale, please be aware that there might be something wrong with the design!
I recommend smoothest fine detail plastic, but smooth should be OK. I have offered Grey PA12 and black PA12 because those work OK for HO (3.5mm) scale chassis though the detail will be softer and the hooks might be indistinct. Grey fine detail and ultra clear fine detail should be somewhere in the middle.
