This is a 45' LPG, tri-axle tank trailer. I have uploaded some photos of the tri-axle and the 'Pup' trailer models. You'll find both the twin axle and a 'pup' version on my HO pages, and I've also released an S-scale version of the twin-axle. I've created a small towing hook on the rear to hitch the pup to and create a 'cow/calf' combo. The WSF material does require a certain amount of preparation to get a smooth finish. I've used an auto-paint, filler/primer and fine grit wet and dry to get a smooth finish on the grey model.
