W.C. Cottier was living in the Island from 1908 onwards and ran Onchan Head Pleasure Grounds. I feel that by 1910 he had stopped the photographical side. I have a copy of The Isle of Man Visitor dated 12th Septmber 1910, there is no mention of a photo studio and knowing the business sence of W.C. I feel sure he would have had an advertisement in the paper. As to 175 London Road I have no record of when W.C. moved out. Sorry I cannot be more exact with the dates.
