Here's a photo looking down Rupert Street to the Hydro plant, 1962. The larger portion of the Smart-Bag Co. building can be seen in the left background.
These two ancient little holdouts probably didn't survive too far after this photo was taken. I'd guess they date back to the 1870s, or built as temporary dwellings during the boom of the early '80s. In the '00s they would have housed a newly-arrived Anglo/Scot laborer and his family, and in the '10s and '20s a Chinese laundry.
