Thanks to Standel for identifying this windmill as the Shiremark Windmill.

American's vacation in England in the 1930s preserved on 25 rolls of black and white negative 35mm film (about 600 photos). Each film roll was marked with a location name. Example: Photo 6-010 is film roll 6 (Blewbury), the 10th photo on the film. The photos were probably all taken within two weeks of each other. I am not familiar with any of these locations. Here is a list of the film rolls that were uploaded and how they were labeled:
