I thought I'd post this short video as it contains clips that might be useful in future builds. It's a pity that some shots are out of focus, but most of the film is clear. You can see Cromwells (7th Armoured Division- 'The Desert Rats), Shermans, 'Kangaroo' or 'Ram' Shermans (M4s converted to carry troops) passing through; and General (or 'Bren') Carriers zipping by- much to the amusement of one onlooker. The camera lingers on the 'FW Woolworth' store at one point. A sign familiar to all Brits, until the 'Wonder of Woolies', ironically, became the demise of that long-standing chain in Britain.
As a once regular visitor, I recognise some of the locations. Do give it a peek

The spectators seen at the end of the clip look delighted at the arrival of the Brits, it has to be said.
