Vintage Cast- Iron

This is a pair of vintage cast-iron tractor pedals. They are in good solid overall condition. They collectively weigh about 6 lbs. 3 oz. They are approximately 4 1/4 inches in length by about 4 5/8 inches wide. I was thinking that these pedals could be used to possibly make wall art/ inner decor or certainly used for utilitarian purposes. So what are the imperfections? There are spots of rust and discoloration spots mainly on the pedals. Please review all pictures carefully as part of the description. Thank you for your time!
