That's interesting. I think that's a Sherman Mk Ib (M4 105mm) on the right. Any idea which unit these tanks belonged to?
As far as I'm aware, the only non-US/French formations to use the Sherman Ib in NW Europe were the 5th Canadian Armoured Division and 1st Canadian Armoured Brigade, as they'd brought them from Italy in early 1945 (every man and his dog had 105mm Shermans in Italy). But from the tracklink fetish, these look like they might be 1st Polish Armoured Division.
