RARE "MILLERS SCALE & BEAM RULE PAT. ORDERED ISSUED"

Regular price $65.00 USD

Fascinating sliding scale rule supposedly used as a grain scale measure. Also labeled "MANUFACTURED BY , OHIO" but someone has carefully rubbed out the name. Research indicates it was manufactured by H.M. Deal Bucyrus, OHIO. Excellent overall condition noting 3 tight checks at 3 of the 4 center ends where the spline reinforces the end. Clean clear markings throughout.
