Today's pic from our anonymous donor has to have been made between 1937 (when 17 was built) and 1947 (when it was renumbered 111)
I can't see the number on the car behind it, but it looks to be of the same series - the final design for Hobart.
I do notice that the two cars have different roof ventilators.
Mal Rowe - rather hoping to ride a Hobart tram one day
