This carte de visite photograph was taken at Porter's Photographic Gallery
located at County Place in Perth, Scotland. John Masterson's rank in this
photograph is Troop Sergent Major, a rank which he held from 1866 to 1878.
Thus the date of this photograph is sometime between 1866 to 1878. The details
of the photograph backmark appear to the right.
John Masterson is in the walking out dress uniform of the Royal Scots
Greys. The most distinctive uniform detail of the photograph is the lace
pattern on the pill box cap on the table. This saw tooth pattern is unique
to the Royal Scots Greys. The details of this pill box are shown to the
left.
