Adapter: Piko 25 Tonner Kadee Coupler

This adapter is made for Kadee's 831 knuckle coupler to fit snug on the underside of Piko's 25 tonner loco. My engine (second-hand) didn't come with the adapter that Piko makes, so I designed this to take its place. It keeps the knuckle as close to the engine body as possible. Probably not a necessary part for anyone who buys a new 25 tonner, but a good replacement part, if needed.
