I have run this on an O-zashiki layout for several weeks. I have checked the vehicle's operation, headlight illumination, and the condition of the pantograph. Attached parts are installed (remaining parts are included). The air hoses have been color-painted. Because the DCC decoder that was previously installed has been removed, there are traces of removal (repair) on a part of the internal circuit board. The skirts on both the 1st and 2nd ends have been replaced with new, re-released parts. (The skirts on EF66 models from this period were too low and would catch on track joints [Kato, etc.], causing damage.) There is a scratch on one side louver (slit) (photo 17). The outer box has some scratches, etc. I have carefully checked everything, but there may be oversights. Please understand that this is a used item before purchasing.
