I'm afraid Shapeways have recently increased their prices on WSF models. This is a 45' LPG, twin axle tank trailer. Mike thanks to Mike Ozosky for the photos of his twin-axle and the 'Pup' trailer before going to the paint shop. You'll also find a tri-axle tanker plus a 'pup' version on my HO pages. I've also released an S-scale version of these LPG tankers. I've created a small towing hook on the rear to hitch the pup to and create a 'cow/calf' combo.
