I posted pics of the truck earlier in this post. Is that the pics you are talking about jake?
This was taken from Earl Madman Muntz wikipedia
"An example of a matchbook ad for Muntz car lots in the 1950s" Note: it says car lots 1950s
And in this book
http://epostscripts.net/writings/46.4post.pdf (as stated by you guys) it says that Earl bought into KF in 1947 and was out in 1948!
but what I don't get is there is a lot of articles that says Muntz had car lots in the late 40's and early 50's as it says in the wikipedia statement. I could probably find a half dozen other places that says the same BUT none of this really matters because if Muntz indeed commissioned these trucks, he did it with 1947 KF sedans in 1947.
On a bigger NOTE: in the Wkipedia "Muntz Car Company" at the very bottom in referances it clearly states
"that Earl Madman Muntz commissioned 3 KF promotional pickups from sedans to see if there was an interest for producing!!!"
More to come
I am having all my findings written up so I can just copy and past it on this Post post
