This kit is from Woodland Scenics which is not the best made kit. It required a lot of filing and filling to make it fit together. The best part of the kit are the tracks and the bucket. I suppose you get what you pay for. This kit requires alot of adjustments. I invested a great deal of time in this build... there were hours worth of filing and fitting it together and once I started I could not let it go. I did put it away 3 or 4 times and would go back to it. It requires lots of bending and straightening of parts and the body to get it to fit together. You fit bend, file, fit bend file until you get it to fit. You do need to paint the inside of the cabs and motor first. I had to file the seat so you could get the cab on and in the end I put the seat in by going through the door. I added the operator the same way through the door. I weathered it with chalks after it was painted. I would buy another one but only to acquire the tracks, bucket and motor for other projects. It will be far enough back in the layout you will not be able to see some of the flaws.
Here are some pictures of the final model
