Chris,
Thank you so much for forwarding the set of "Z" suffix coded P-40's based at Moore Field ,TX! Up to now every aircraft I have noted flying from Moore Field displayed only numerics. You certainly have made a contribution for my database! As Tom (aka "res6kgcr") stated the Central Flying Training Command is really a "can of worms". I've trying to figure out their structure of letter coding and have concluded there is none. The WFTC and EFTC is quite orderly and does make some degree of sense as they used a Prefix system for their letter coding.
The CFTC is basically a mishmash of Prefixes, Suffixes, Infixes as well as no letter coding whatsoever. If the intent was to confuse the enemy they were certainly effective as we remain confused ourselves seventy years later. All I can do is to document what I (and others) find and hope that one day it will all make sense.
I have posted one of your Moore Field P-40 images to my website (
http://www.fuselagecodes.com) under the subsection of "Transition Fighters" and of course gave you the credit as the source.
Thank you again for thinking of me and of course contributing another missing piece in the on-going puzzle!
