I haven't looked for date codes on distributor plates, but was looking through some of my pictures and noticed this upper plate with the Autolite symbol and a date code for October 1929. This is the first and only time I recall seeing a date code on the top plate.
Also notice the worn insulation on the left, and the incorrect wire on the lower plate on the right. This is ordinary primary wire with stiff insulation, and will break after moving the top plate back and forth several times. You can see several strands are already broken from flexing, and it only is held in place by a few strands. The dealers have the correct very flexible 100 or more strand wire. Distributor Plates.JPG
