Superb, I really enjoy this figure, but why put an helmet ?
I explain the main differences with British soldiers in WWI was at the beginning, the Ross Rifle Later abandoned the profile of the English gun LEE ENFIELD.
The Ross rifle
Lee Enfield rifle
But the biggest difference, and it gets interesting, badges worn.
Cap badges, collar badges, shoulder and arms badges, usually made of copper, but also very beautiful.
It was not that the maple leaf and the title Canada, many others have been worn, especially by the NCO, proud of their original battalion.
A famous example of the 22th Battalion.
This one was worn as Capbadge and collars badges, title shoulder/arms Canada
Other version of title exist,there's the more common.
All this to say, as your figure seems to "rest", why do not represent wearing a cap with the badges you want?
That would make more Canadian.
For Canadian badges, three reference books:
The Cox- Military Badges of the British Empire 1914-1918 by Reginald H.W.COX, publisher, The Standard Art Book co.Chicago, Illinois no ISBN
All the cap badges worn by the British Empire Forces during WWI, all photos are that of cap badges full size, some photos of collars and title 1/2 full size.
A must have all British, Canadian, Anzac, Indian, African....All the British Empire!
the second and third, the Charlton's reference guide, is for collectors, but referenced all Canadian cap badges with their estimated market value. Phtos versions and often collars and titles.
I am talking about them, but it is now almost impossible to find
In case the books references :
The Charlton price Guide to First world War Canadian Infantry Badges, by WK CROSS, The Charlton Press, ISBN 0-88968-081-7
The CharltonStandard catalogue to First world War Canadian Corps Badges, by WK CROSS, The Charlton Press, ISBN 0-88968-162-7
