16th Battalion (Canadian Scottish) looking for info on old photo

[Nomad]

I can't say about the tartan, but I fancy the picture was taken in a studio(a perfectly normal thing to do) before he fully passed out. Why? No unit insignia on his tunic, no wound stripes( which he certainly earned and were I think, still worn in 1918/19) and no medal ribbons ( he would have at least one "Campaign" Medal). Which he would have by the end of the war.

Some very astute reasoning jock, I think you are probably correct (to me the big giveaway is the 4 ft of white wall, where else but a studio would you find one of them )
