Nice work Paul. OFCC North #16 it is. Love the open look over the holes behind the green.
The second photo is definitely from Weston, MA (
http://westonhistory.org/Extra-HTML-pages/Coburn-Gallery.html). There are three courses that it could be, Weston GC (1894 - Harland, 1897 - Findlay and 1916 - Ross) Pine Brook Valley GC (1924 - Stiles and Van Kleek) and Drabbington Lodge GC (1924 - Unknown). Being able to narrow down the date might help.
I think the third one may be from Janesville, WI. Possibly the Janesville Municipal course by Harris, which may have been renamed at a later date.
