Steve that is definitly the Bates Mill. My guess is that it is at an earler date based on the appearance of one smoke stack in your photo and two in mine. In SVRR's Emlaw Collection there is a photo inside the power house which included a 500KW steam turbine driven generator to power portions of the mill and the town. I don't know when it was added, but it might account for the extra smoke stack needed by more boilers to provide the extra steam. Here is another photo of the mill from the same group of photos from my collection.
