I bought these two "kits" from Shapeways a while ago and recently completed them, they make into a couple of nice models. The first is a kit of parts to make a Rumania Kraus (Linz) 0-6-0T loco using a Roco BR80 loco with heavily modified body and the second is a kit of a cab, rear bunker and chimney to concery the Roco HF110c tank loco to a Reista look-alike (missing one axle!).
