Notes: "The Dietzgen model 1735 Vector Type Log Log Rule is Dietzgen’s large, duplex slide rule with three hyperbolic scales. Aside from those three scales, it is entirely a conventional log log duplex slide rule with 5 log log scales covering the range: .0001 to .999 and 1.01 to 20,000. The construction is celluloid on mahogany, with steel end braces (very K&E-like). The all-metal framed cursor is especially nice. "
