This On30 shorty tender is a great addition to any Forney , Porter or any logging steam locomotive. It is 3D printed PLA plastic. Your wheels and couplers are required. Comes with everything you see in the photo TenderBody, Rear step bumper, Truck w/mounting screw, Tender top, tool box, Brake wheel and Shaft, Coupler covers and screws . Buyer has little preparation that maybe necessary for a slight adjustments. Removing some flashing and slight sanding with surface preparation is needed for completion as is in any kit. Great looking add on piece to your locomotive. The completed shorty tender and Locomotive are for reference only and is not included in the kit. Again for reference only Thanks for looking and happy railroading
