Does anyone out there know if Caterpillar made a horse drawn, bottom dump, gravel wagon about 75 or 80 years ago. My Uncle owes one that he has restored but he couldn't find a manufacturers name. He believes it is either a Caterpillar or a Hough. I have pictures of it so if you think Caterpillar made a wagon like this, contact me and I will email you the pictures to help you identify it. Thanks for any assistance you may provide.
