There is conflicting information about the All-American. One report has him being killed by a sniper's bullet in the Korean War. While Elliot Mills mentions that the All-American along with the Lamplighter had just retired in 1959.
There also could be some link between the All-American, Slugger, Commando K/Commando K Project and U.S. Government involvement which would show how all these are related, if at all besides what has already been established.
