Dietzgen"National"Slide Rule 1767P in Sheath w/book This is a vintage DIETZGEN " NATIONAL" SLIDE RULE in original SHEATH with the original Instruction book My dad still uses his for doing estimates in construction...don't have to worry about carrying a bulky calculator or dead batteries with this! If you are an engineer or know of an engineer..this would be a nice gift for them..if they don't use it, they could at least put it on display.
