Hi rlahammer, my story is similar to yours. My grandfather sold KF at Triangle Motors in Jacksonville, FL. My car is a good daily driver but I am working to get it to more of a show car. My questions have been mostly of a technical nature and I have gotten a lot of good responses. I have probably been on this site for less than two months.
My car turns heads and I am surprised at how many folks even know what a Kaiser is. I live in a small town in GA and evidently back in the day they had a small KF dealership. I have a 1964 Ford with a 427 that would bring probably 5 times what the Kaiser would and its in a whole lot better shape (it is in a condition that it could be shown) but it does not draw a crowd like the Kaiser and to me 49 was not the pretest body style.
I don't have any thing except for newspaper advertisements my grandmother collected in a scrap book and some moving family films of the dealer/distributorship. I have been hunting for some neat stuff like signs, poster and so forth but have not found much available. I look mostly on Ebay or Craig's list. I run a railcar repair facility and do a lot of business with folks like Fastsign and have though about using some of the electronic images I have of advertisements reproduced into signs or posters. Since I'm not at that stage yet I have not priced them. I would like to own the original stuff but wonder if it would be more affordable and easier to have some reproductions made. In the movies my grandfather had some pretty neat posters in the background for a Virginian. Give the cars on the showroom floor I would date the movies to 1949, hence I have a 1949. The car came from Florida originally, it would be neat if I could trace it to his dealership, but that is impossible.
