5-plank wagon conversion

So I got a bargain on an online auction, it was dark grey with 'loco wheels only' markings, but with a 'coal load' glued into it, I have to admit I was more than a little disappointed. Originally (before I found the 'coal') thought it would go into store for a steam era idea, but gouging the load out would still require making-good afterwards, so now I've decided it needs a new identity.

First some bauxite paint, then a simple renumber

then a tarpaulin sheet for the body

next a revamp for the underframe, wheels, brakes, vac cylinder, tie rods etc
