Agreed the attached map from the SLV collection possibly dates from around 1860.

It shows a blank in the area between Flinders St and the Yarra, and probably misrepresents the actual alignment of the M&HB railway bridge.

Some of the map is probably conjecture.  M&HB railway opened in 1954, Parliament house started construction in 1855 and the government railway terminus at Spencer St was established in 1859.

If I'm correct about some conjecture - then the date may be around 1853.
