Research: The Thames from London to Oxford in Forty Photographs, First Series, Virtue and Company, London

[Mrs. Joan Osmond]

The publication date of 1862 has now been called into question. One of the photographs must have been taken after 1863. At that date the Curfew Tower of Windsor Castle was altered. Victor's photograph shows the new tower.When was the Album published? It must have been between late 1863 and early 1865.

I would be very grateful indeed for any help on this.
