Notes: "The Dietzgen 1762B Multiplex slide rule is a straightforward Mannheim slide rule with the addition of a K scale, labeled “E”, on the lower edge. The front face consists of only the original Mannheim scale set: A, B, C, D. The back of the slide has S, L, and T scales, and the well under the slide has nothing but bare wood. The cursor for the cube scale on the lower edge is a line scribed on an extension of the metal cursor frame. The slide rule looks very K&E-ish, and may have been made for Dietzgen by K&E. "
