Anyone Seen These Drawings Before?

Unfortunately, ALL of the previously surviving paperwork, including ALL of the microfilm aperture cards and a couple of truckloads of paper and ancient waxed linen drawings from the old "towers", were sent to the "Powerhouse Museum' in Sydney. . . .

I would think a better place for all that would be the National Archives or National Library in Canberra.
