Bought two identical kits to be used as farm implement loads for HO scale model railway flat car loads. Each kit went together reasonably well. Castings were quite clean needing very little clean up. There was one part missing (same part in each kit) but fortunately it can be easily replicated and added to complete the model. Instructions were fairly easy to understand.
I've built one of these kits before. They go together quite well - with some correct John Deere paint it looks just like an HO scale 12A harvester. Now to find a case pull type and a Alis Chalmers 66
