When I saw it last night for an instant it looked like G 1 that was scrapped forty five years ago however when i zoomed in it did not.
That is why I asked the question do you know the code.
On reflection it looks like the hopper that use to be on Echuca wharf and somewhere in my mind several items there were removed.
I do agree it does not look like a standard O/ON hopper.
All part of the fun of looking at the background of photographs to pick up unusual or items that were not the feature/focus of the photographer.
Thank you again, PTE.
