At our convention this year, there was some discussion around exterior sun visors and mirrors and their availability. Attached are scans of the accessory bulletin display sheets for each.
For the sun visors, I've included two scans - the first is from 1948 and depicts the new 1949 Kaiser. The second scan shows a visor on a 1951 Kaiser. Once KF went to a one piece windshield, a third version became available and once I find that bulletin, I'll scan and add its image.
I also included a scan of the Henry J wind guard accessory. While we didn't talk about it, I found it too neat to ignore. It was introduced on March 15, 1951 via bulletin number 46-A.
