The Sikh man sitting in the lower right has never been identified. If you have a clue who it might be, you're asked to contact the British Columbia Regiment.

The British Columbia Regiment is asking for help identifying a mystery man in a 100-year-old photograph.

The photograph has been hanging on the walls of the regimental hall in downtown Vancouver for decades.

It shows rows of sergeants and warrant officers as they posed for an official portrait in 1913.

But among the soldiers is one anonymous Sikh man in a suit and white turban, and there are no records explaining who the man is, says Warrant Officer Ron Leblanc.

“It is certainly interesting, because you look at all of the other people in the photo and they are all white males and then we have this fellow and he is there,” LeBlanc says. “He is right in the front row and sitting in that prominent position.”

Leblanc hopes anyone who may know the man will contact the regiment.
