These, somewhat idealised images, were produced as a part of a series of postcards for sale, by Cammell Laird, and proceeds went to the Red Cross war effort. I doubt that working conditions were anything like that portrayed, but I like the paintings, it conveys some sense of what it might have been like working in one of the large saw makers's factories around the early part of the 20th Century. Just about every large saw maker also made files. They used some of the files produced in their own saw manufacturing, after which used files were re-introduced into the steel making processes.
