Acquired these a few years ago. Unfortunately, I didn't spend as much as I should have to get all of the associated documents as the dealer went out of business shortly afterwards. Quite the array of units assigned to the Ohio ORC.
I believe they belonged to Col. Coleman B. Todd, FA-RES as his name is highlighted on most of them. He was an enlisted man in Battery D, 135th Field Artillery, 37th Division during WWI. Between the wars, he was an officer in Battery D, 134th Field Artillery, 37th Division, eventually becoming XO of the 1st Battalion. He was called to active duty with the division. In civilian life, he ran an advertising agency, Coleman Todd and Associates.
