Geoff;
Can't seem to find an exact location of the bridge in question. The original caption for the picture reads " NO BRIDGE NEEDED HERE - Dominions troops are now receiving instruction in anti-invasion tactics at a military science college in the north of England. Dispensing with bridges, a lorry is here seen towing a gun and limber across a river."
I can't make out the shoulder flash of the Sgt in the lead gun tractor, looked through Vol II of the history of the Royal Regiment of Canadian Artillery, but couldn't find any clues has to location.
Maybe one of our friends in the UK could help us out on the bridge location?
Cheers
