Wow Bob, thanks for sharing. I questioned the green lettering to start. From some older Autolite ads I've acquired it seemed that yellow and red could be colors for OEM Autolite batteries, while green was a lesser quality/cheaper line for service replacements. They also had a higher quality/ more expensive gold lettered also. The owner of that R model seemed pretty adamant about it being correct in the article, go figure. Never mind the Prestolite knowledge.
