Ok, I got it, Kaiser Motors (formerly Kaiser-Fraiser), merged with Willys-Overland in 1953, so "The Mad Kaiser" is a nickname for a Willys that I've never heard before. Bitchen find, whatya gonna do with it?
Wish I could help you out but it does not bring back any memories. Good luck with whatever you decide to do with it. Nice find.
A Kaiser motor in C/Gas I don't think so, maybe the owner/driver was named Kaiser. I love it, I would get it together like it is.
