Attached is a copy of the chart from the back of the 1941 shop manual. Copy is not perfect as the original is very worn. My scanner could not process it in one scan, so there are two pages which can be spliced. The original is approximatly A3 size.
The scan was done at 1200dpi then, reduced to under 2 meg to fit on this site. If greater detail is needed, I can send the original .jpg images separately by e-mail (8 meg and 9 meg).
