I've now had the chance to paint up one of the prototype prints of the A.G.W.I. Oil Refinery flat wagons (see here and here for previous posts) along with painting the Peco oil drums to hide the rather garish plastic colours.
I'm really happy with how these have turned out. Having worked from just four photographs I think the end result looks pretty much spot on. If you want some of your own they are now on sale in sets of four (they seem to have always been used in sets of four and this also made most sense given Shapeways pricing formula) from Penistone Railway Works.
