The water fill point has been changed out and you can see some work has been done around that area. It looks like the red wheel spokes have been repainted. The red/yellow on the upper drive wheel looks to be original however.I have no idea if it works or not. My father has had this for a number of years and never tried to get it going. All in all it is a cool vintage toy set. The item "Weeden steam engine tractor plus 3 tools Saw Grinder Stamper 643" is in sale since Sunday, January 15, 2017.
