This is an old Roco/Con Cor caboose. top picture is original. The bottom picture is just 5 minutes tinkering. I put it on an MTL dorky "Pepsi" caboose. It fits perfectly, with very little mod. All I had to do was cut off the tabs that held it on the original chassis, and trim the edges to match the steps,and walla.. Now all that needs to be done is a little work on the ladders, paint and detail.
