Quote from engineer on June 20, 2013, 5:09 pmHibler and Kappen use 243 for the Type II McCormick Reaper piece, then A, B, and C are used for the "managers" pieces. I recently acquired a third die pair combination of 242-243. I guess one would use 243A to be appropriate, but D is the next letter not already in use. I have pictured the image with the obverse and reverse as designated by Eglit which is the opposite of H&K. The die combination is similar to H&K 243 with the following differences: The initials, OA, appear on the bust of McCormick, but the S.D. Childs, Chicago signature is missing. Instead of a beaded border, the boarder is denticulated (is that a word???). Look below the reaper and you will find the patch of ground below the wheel on the right is missing.
