The templates were used for inked lettering on architectural & engineering drawings or maps. Two are 12" (11-7/8") long; 4 are 9-1/2" long. Templates have company name: K+E Leroy and the product number. While the count is correct, one of these templates is definitely not original to the set, but was apparently a later addition/replacement: 61-0300-100CL. Also the "3240-80C" ('C' is for 'capital' and 'CL' is for 'capital and lowercase') should have been a "CL" and is presumed to be a later substitution or replacement. The varying condition (ink marks, differing degrees of whiteness of the plastic) also suggests that this not an original set as sold. Present in this set: 3240-80C 3240-100CL 61-0300-100CL 3240-140CL 3240-175CL 3240-240CL Scriber does not have product number, but does correspond to N3237-2, Adustable Scriber, as called for in the boxed set. Date that plastic knob fitting came into use was circa 1941 or later. Keuffel & Esser Co. was located in Hoboken during this period and the item is considered as having been manufactured here. Instructions copyright 1950, but date of manufacture or issue may have been during the 1950s and possibly into the 1960s.
