Hi Wim,
Your posted picture is very small but I don't think it is a Sherman Kangaroo. To my knowledge no Shermans were converted to an armoured "Carrier" role in the NWE theatre.
This tank (and I had a hard time making it out as a Sherman!) has a lot of stuff on it, it is most likely an armoured recovery vehicle? But then, almost anybody else on this forum is better with military vehicle identification than I am

Bill.
