K&E 4181-1 ---- 1966-1972 68 1282 in 1960s Style Packaging
From the collection of Clark McCoy
Note: This rule does not have a model number printed on it. Probably the rule was made from the same tool used for the 4181-1 with the model number removed. It was difficult to add lettering to the tools but rather easy to just remove lettering. There is a 1966 copyright date on the front of the packaging.
