These photos appears to be from the early 1900's, judging by the use of steam power on the job site. These were sent in by Dave H., who's grandfather took these photos. He was born in Hillsville, PA, in 1895 and lived in Lowellville later in life, working in the mills until a fall broke both of his legs. I am told that he had a passion for photography, and shot and developed many photos of steel mill construction. I am looking for any input as to what mill is featured in these photos. It is possible that this is Youngstown Sheet & Tube Campell works or Sharon Steel Lowellville works. Lil help?
