Thanks!
Actualy yes! i modified this: marklin 58701.
I bought few years ago one in really bad condition wagon via ebay . my original plan was to renovate it...
I just kept the original chases all other parts made by me like Y25 boggies or full body.
I cut the puffer parts , and i brushed the sidewalls as well and i replaced with Res type one..
