50th Gordon Highlanders. They were a pre-1914 militia unit formed in Victoria British Columbia. (Sir Arthur Currie helped raise the regiment in 1913.)
The 50th Regiment contributed volunteers to the 7th Bn and the 16th Canadian Scottish Bn, among others at the outbreak of the war. The 50th was amalgamated with the 88th Regiment, (Victoria Fusiliers) to form the Canadian Scottish in 1920. The Canadian Scottish perpetuated the 16th Bn Canadian Scottish of the CEF.
The 50th, as a Scottish regiment, had the sporran badge.
When the 16th Canadian Scottish was formed in 1914, it had companies from various Canadian Scottish militia regiments. No 1 Coy was the 50th Gordon's, No 2 Coy, 72nd Seaforths, No 3 Coy, 79th Cameron Highlanders (Winnipeg) and No 4 Coy, 91st Highlanders from Hamilton. Evidences indicates that the battalion proceeded overseas with the parent unit insignia.
The 50th Gordons also raised and sent a large draft overseas during WW1. They were badged to the regiment.
