Hess & Eisenhardt Coachbuilder Data Plate - Lubrication Chart & Serial Numbers

This photograph shows a manufacturer's data/specification plate riveted to a vehicle body, photographed upside down and partially obscured by dirt and corrosion. The plate identifies the coachbuilder as The Hess & Eisenhardt Co., 8959 Blue Ash Road, Rossmoyne, Ohio, with the heading 'Custom Built For.' The main body of the plate is a lubrication recommendations chart, stating 'We recommend the use of high grade products such as the following,' and listing Mobil-brand lubricants for various service points: engine oil (Mobiloil A.F./10W for cold weather), rear axle (Mobilube 90), steering gear (Mobilube GX 90), chassis fittings (Mobilgrease), an air cleaner entry, and several other rows that are only partially legible. At the bottom, stamped serial fields include ENGINE NO. (appearing to read approximately 5562699[3]8) and MFR'S. NO. (approximately 32500), plus a MODEL NO. field. A stylized H&E script logo appears near the serial numbers. Readers can learn the coachbuilder's identity and address, the factory-recommended Mobil lubricant grades, and the stamped engine and manufacturer serial numbers, though several table rows and digits are too worn or out of focus to read with certainty.
