When I was diving in convoys I was driving the MLVW, Itlis, 5 1/4 and M113 (Anti-Armour 3 PPCLI) all but the Itlis had a full set of flags and the Itlis had a yellow one in a bag. The M38a1 was out of service when I joined so never had any personal info on them.
(A side note) I chose to buy a M38a1 over the Iltis becouse I knew how we used to treat that poor little thing.
Thanks for the info.
