Service Information Bulletin B-18, dated October 20, 1942, item 30, Windshield Opening Revision.
“The windshield throwout arms “A” Fig. 1 have been revised on the new style cab to increase the windshield opening by changing the arc through which the windshield travels from 30 degrees to 90 degrees, Fig. 1. This facilitates the use of Fire Arms through the windshield opening and became effective commencing Serial 2844409695 on all Canadian Military Pattern Vehicles, except Heavy Utility when the change was made commencing Serial 2844513801.”
