Prefixes of U.S. administered callsigns prior to WWII were very different to those in the post-WWII period.
However, the pre-WWII prefixes continued to be used for a short time after the end of WWII, and thus are of interest for Club Log.
As far as I can ascertain, new prefixes began to be issued in early 1946, and the changeover was largely complete before the end of 1946.
Known prefixes (this may not be a complete list), including Club Log mapping dates - log in to Club Log to view QSLs (not necessary for K8CX QSLs):
