The first time gun at Edinburgh Castle was
installed in 1861. It was linked by an electric cable to
the time ball on the top of the Nelson Monument on Calton
The time ball was raised daily, then dropped at 1pm, to
give an accurate time check to the shipping in Leith Harbour
and to others who were able to see it.
The time gun was introduced in 1861 to give an audible time
check at 1pm, for days when the weather was misty and the time
ball could not be seen.
This map was produced to show how many second it took for
the sound from the one o'clock gun to travel to different
parts of Edinburgh:

I believe that this card probably dates from the early
1900s. There is no publisher's name on the back of the
card, but there are initials- 'cZco' or similar - on the front
of the card.
Do you know who this publisher
might have been? If so,
please email me. Thank you.

I am currently trying
to find out more about this printer."

Thank you to Fiona Mackintosh, Edinburgh who wrote:
"I believe Zinco
Collotype Company was my grandfather's company. He was
George Thomson, and he was in business with
his brother-in-law, Arthur Dunbar, and one other.
George's daughter (my mother)
says that the business was forced to close in the Second World War,
because it was considered a luxury and not sustainable during these times.
The family lived in Bellevue
Road. To the best of my knowledge, the above is correct. I don't
imagine that there were two collotype companies of the same name in that
street, although my mother says that the premises were not next to the
library, as suggested, but near the junction
with Hopetoun Street."
