They hydrant has since been replaced with a new McAvity Brigadier, so the model wouldn’t match, but the location of the hydrant matches.
I do have a concern about the utility pole, though. In our mystery photo the pole is ahead of the front of the house, with the lamp facing us, but in the Archives image the pole is behind the front line of the house and the lamp is facing the wrong direction. However, the Archives image was taken in 1913, and road work could have been done later. If the pole was moved from Hamilton to Dundas it could explain why the house has an unused walk-up. Having said that, I think this intersection remains an excellent candidate as I review further evidence.
My many thanks to all the members of the UT History Squad who gave up personal time to chase my obsession!
