Hi guys,
Found this picture in a veterans photo gallery labeled Lima Platoon, C Troop, 1/4 Cav, Vietnam 1969. Unit, area and year made me speculate if this might be the M41 hidden in the bunker found by scout Bob Davis and described in chapter 10 in Mr. Mills book? I can't think of any reason why the ARVN would drive one of their tanks into such a position so I assume that it's one that got "stolen". Perhaps there were more than one M41 lost (and later found). I have to admit that I'm hoping for a reply by Mr. Mills 
.
