This is a 3mm:1ft scale model of a Great Western Railway Loriot L (G13). It comes with wheels and coupler pockets to mount under the floor ends (glue). You could also add a couple of DC III brake levers to the v-hangers at one end - I have uploaded some TT120 ones that are about right for 3mm (and maybe a bit big for TT120). Please read the notes for the TT120 and 2mm:1ft models like this one, as the same advice about fitting the wheels applies. The wheels here fit FS track (14.2mm gauge) and have axles 20mm long. These finscale wheels and the recesses in the underfloor of the body in this model are designed to fit them. Other sorts of wheels may not fit, and the spare wheels may not fit other models. If you use 12mm TT track, please consider the LoriotL_3mmTT and LoriotL_3mmIS models instead.
