The influential distributor and manufacturer of mathematical instruments, Keuffel & Esser, introduced the Paragon line of drawing instruments in 1901. This set resembles the wallet case sold as model 624AC in 1921 and in 1927 and as model 624ACRX in 1936. The markings are more like those shown in the 1936 catalog, but a horn center sold with that version of the set is missing. The price in 1936 was $39.75. Since the set was imported from Germany, K&E was not able to offer it during World War II. When sales resumed by 1954, the joint tightener was no longer included in the set.
The owner of this set of instruments, Isaac Giancinto Molella (1908–1982), was in the Cornell University class of 1932. In the early 1950s, he worked as an electrical engineer at General Electric—at Electronics Park in Syracuse, N.Y., in 1953, and as a technical representative for the U.S. Air Force at radar sites in North Africa and Europe between 1954 and 1957.
