Thanks to Andrea Woods Gonzalez for this photo. She doesn't have the photo in her posession so she can't remove it from the frame. She's trying to identify her uncle, Stan Trowbridge. Hand lettering says "Kerr-Addison Mines / July 6, 1936 / Larder Lake, Ont."
I posted this photo in the 'V-town/Kearns' Facebook group and so far have had two responses – Front row, 2nd from left (with head-light on) is Clyde Furlong; 5th from left is Steve Stratford.
