This is the steam shovel Oscar Lundwall, my grandfather ran in the iron mine, he is sitting directly in front of the shovel window, and could only be identified by his ears, the darkness of his eyes, and his posture and comparing it to his wedding photo from 1908. lol -- it is a photo I found in my parent's photos from the 1900's.
Here is the closeup of the man he matches.
I was only able to identify him by his facial structure, his ears, and the posture compared to his wedding photo below. I also remember that he always wore a cap with a bill on it to the mine when I was a child.
