Hey Blane, I think you could be right there, I brought up Windsor St on Google Earth and I can see a bridge on the photo which seems to match to Aston bridge on Aston Rd.
There are three gas holders on the site now, so if it's the right place another gas holder would have been added, they are very close together. There's a building between the two gas holders in the photo, but it's not there in G'Earth. However there is a new, lower building and some evidence of old foundations.
