Discussion Points:
The earliest available drawing is dated 7-7-30, at EI 15206 Supp #4 release, and shows the stamped steel hinge clip, and the optional steel sleeve hinge design. The hand crank angle is formed by 90 degree bends.

The next recorded drawing is also dated 7-7-30, and is the checker's markup record to the detailer for subsequent changes, and shows the stamped hinge clip erased out and to be removed, an angled hand crank end, and the hand notation "redrawn and changed". Though this is 'dated' 7-7-30, it is actually the marked-up direction for the changes made and recorded 10-31-30.

The next available drawing is dated 10-31-30 (EI 15206 Supp #6), and is the newly drawn handle, which only shows the sliding sleeve design hinge, as well as the angled hand crank end. Also, the revision block has been reformatted, and earlier EI 15206 Supp #1 and EI 15764 no longer appear in the record.

If any of the early 1-10-30, 1-18-30, or 3-6-30 dated drawings were found, they might show a later introduction of the sliding sleeve hinge design. Until such drawing is found, it should be assumed that the sliding sleeve hinge design was always an optional construction beginning 1-10-30.

It is my belief that the JSC should accept the stamped steel hinge clip design handle starting in January 1930 through end of October 1930, and that the first sliding sleeve version should be accepted from January 1930 through May 1931.

Starting May 1931, the hinge rivet axis was rotated 90 degrees to allow the sliding sleeve design handle to fold across itself forming a triangle, and this design was used through the end of production.
