A fine looking gent indeed.
Systemic Wild Ass Guess (SWAG) considering the red tunic, blue or black facings and white plume:
British cavalry 1. 4th Royal Irish Dragoon Gds (bandsmen of the Royal Dragoons, but no lyre worn on the sleeve.
British Yeomanry: 1.Montgomeryshire 2. Royal Berkshire 3. Fife and Fofar 4. Duke of Lancaster's Own
(considering the Canadian source, the Royal Canadian Dragoon wore a white pith helment, not a metal helmet)
This will narrow it down some what, and I am sure someone will disagree.No harm done. Hope this helps.
