Kimes and Clark have the following to say about the Gramm Steam Car.

In 1902 Benjamine A. Gramm, general manager of the Motor Storage & Repair Company of Chillicothe, announced his forthcoming manufacture of steam carriages in the $750 to $900 range. The Gramm steamers were built for one season only.

In 1903 Banjamin Gramm switched to a gasoline surrey that he called the Buckeye. The year following he remained with gasoline cars, but switched the name again to Logan.[1]
