I own a Model 18 Combine; it was the 241st one built and has only had about 300 acres run through it. The original rasp bars still have sharp edges. Mine was very well taken care of and sheded most of its life until about four years before I bought it. I can tell you that my reel is white oak and were painted green. Come to the Albert City Show this late summer in Albert City, IA. I&#039;ll have the combine on display with a 1954 Oliver Row Crop 66 diesel. Good Luck with your project!
