At first glance the two Conklin pens in this article could be Endura Symetrik pens from 1930s. They have all the elements shown in the A. Bienenstein Symetrik design patent, D83,592, awarded March 10, 1931: a rounded balance shape, a spring loaded clip, two cap bands, a crescent symbol on the cap, and a crescent symbol on the nib. The clip, the 1936 Conklin patented type, and nib, a Cushon Point type, could date the pen possibly as early as 1936. The barrel imprint tells a different story. It’s stamped THE Conklin PEN CO. over CHICAGO, ILL. U.S.A. over ENDURA – D- 83592 over REG. U.S. PAT. OFF. This is a Chicago Conklin. A Chicago syndicate consisting of A. J. Parrson, M. H. Jacobs, and Max Horwitz purchased Conklin on July 13, 1938, and moved existing stock of unfinished pens and parts to Chicago. This dates it no earlier than mid 1938, and likely later as there would have to be some amount to transition time from Toledo to Chicago operations and production.
