Sydney Harbour Bridge

Only the second example I have come across from this little-known maker of plywood puzzles. Both have come from Australia, so I presume that they were either manufactured there, or imported solely for the Australian market.
I would be very pleased to hear from anyone who can help me with any further information on the manufacturer.
