The event was at Bovington tank museum in th UK, its the annual aromour show that they sometimes theme this particular it was American vehicles, the Grant was in running order & done several laps around the areana much to everyones suprise, the driver sat on a wooden box as there is nothing left of the interior as it spent many years as a range target, they decided not to restore it but to leave it as it is which is a shame but understandable when you have a good look at it
Thanks for the comments, a lot more to follow
