I have 4 chips used at 24845, 3 are hubs. They are inlayed hubs so no records exist in the Mason files. If we ever get access to the Burt records they might be there.
I got mine from Mike Spinetti in 1998.
He got them from Hertz. Hertz told Mike they were purchased from the estate of Linclon Fitzgerald. Fitzgerald opened the Nevada Lodge in Tahoe, 1958. Prior to that he owned the Chesterfield Club and 24845 in Detroit. I believe he was also involved in other illegals in Detroit 1920's-1958.
