Hi all, Need a little help, has anyone got details of the radiator overflow tank fitted to the Canadian universal tank hunter carrier, all the pics i have seen dont show the tank in the normal position, is the Mk2 carriers overflow tank the same as the Mk1 overflow tank also?. On a three inch mortar carrier it appers on the rear armoured air box on the left hand side, I can borrow a MK2tank but need to know if it is the same on a Mk1.
