One question: Both in the game and in modern satellite views the tall rectangular tower at the southwest end of the elevator has a 5- or 6-story "shoulder" on the northwest side. RO2 players can climb a fire escape that offers access to the top level. In historical photos, however, I see only a couple of much lower structures on that side. In fact a model of the grain elevator for wargamers also lacks the shoulder:
So was the shoulder missing in 1942? The game depicts the modern layout?
OK, that was two questions. :-)
