Hello everybody!   I've finished building/converting the last of the TPM tipplers:     I bought quite a few second hand, they were quite bowed - but I'd also separately bought a lot of side/end sprues without a floor-unit.  I soaked out the load and then cut the sides/ends off and replaced them with fresh ones.     The bogies were built long, so I re-assigned some shorter ones from some random hoppers I found in the wardrobe (don't remember buying them, not sure why I bought them)
