Sav, I have larger versions of the kilt pics, if you're interested. Were the Highlanders British soldiers, or were they from one of the colonies? There wasn't much info at the museum as to which army units were there. Since I've been home, the only reference I can find to the Cameroon Highlanders was to the Canadian Cameroon Highlanders. Is that the same unit?
That would be the Cameron (79th) Highlanders, not the "Cameroon" Highlanders. Cameroon is a country in Africa and was at one time, a colony of Germany (Kameroon) that was taken by the British during the First World War.

The other kilt appears to be Mackenzie tartan, making it a kilt of the Seaforth Highlanders.

And to my knowledge, no Canadian forces served in India -- the first time the Canadians went "overseas" was in the South African (Boer) War.

Regards,

Todd
