A canadian badge (172nd Battalion Canadian Expeditionary Force) outside a camp thought to be at Bramshott near Aldershot, England where they were stationed during late 1916. The BC denoted British Coloumbia where the unit was from. They were commonly known as the "Rocky Mountain Rangers". It was common for the Canadians to make insignias outside their camp when stationed in the UK.
Many Thanks to the Canadian War Museum for their help
