When I was last in Manchester, I had some time so I popped over to the Salford Quays to visit the Imperial War Museum North.
They have lots of smaller items and the displays are both fascinating and informative.
They do have a Matilda II infantry tank.
This is a British WW2 infantry support tank, crew of 4, powered by two Leyland 6-cylinder diesel engines, armed with 2pdr gun and machine gun.
This tank served with various Royal Armoured Corps training regiments within Britain.
I do have an old 15mm metal model, but that is still on the workbench since I bought it in the 1990s, typical wargamer!
