Hello Dave
Having done research on the WW2 jeep i can honestly say NO there has not been any central records kept on Jeeps.
I, as well as a few others have been collecting data over the years and created our own lists. If you were to provide me what data you have i.e. the serial number and any vehicle markings i can look up on my list and let you know if i have any data on it.
Thanks
Eric
