This photo was taken January 1, 1917 in Nova Scotia. It is on file at the NS Museum of Cultural History.
It is hard to tell, but if you look closely you will notice that the two men who are not wearing hats are wearing leather aprons.The men work for The Eastern Car Co. Here they are taking a mid day break for the camera. They work with a big machine called a lathe. A lathe spins a block of material to perform various operations such as cutting, sanding, knurling, drilling, and gives it symmetry about an axis of rotation. The pieces seen here laying on the tables are train axels. As it turns out this picture has been turned into a postcard.
