Need your help again

I have these blueprints no1 to no4. But can’t find them. I have only photographed no1. As always, your help is always appreciated.

I think none of them have been catalogued yet. There is a windmill entry, which is gear (https://www.brickowl.com/catalog/lego-windmill), but it has next to zero info and given the lack of Boathouse, Astronaut and London Bus on the catalog I would be fairly certain this is not what you're looking for. BL have all four listed as books (kind of an early version of Ideas books) rather than instructions as they don't link to a set.
