Have this sickle head and no use for it. It appears to be NOS. The only identification I can find on it are the number 100207 and another which is hard to read the first digit, appears to be 901041 but the 9 is not clear and could be a 3 or 8. It is 18.5" overall and the bearing end, which has two snap rings, is 1-5/8" in diameter. Any help on what this might fit is appreciated.
