The top right and bottom left turbines are, I think, the same as in post 7 & IIRC the bottom left in post 1 is the same exact turbine.
As for the rest I've no clue how old who made or anything else. From what limited reading I did today, the problem remains the same under abnormally high winds that are sustained for a length of time. The brakes/gearboxes overheat and fail.
