This is the tower WAAF (107.3 Westborough) is currently licensed to use. According to the FCC's Antenna Structure Registration database, this tower was built in 1933, but one strongly suspects that this is a mis-read for 1938, which would fit better with the chronology of W1XOJ's construction in the late '30s.
