There are MANY collectors of Aden, especially of the Indian

Aden Cantonment was one of the MAJOR post offices of Aden.
It was located in the town of Aden, which is located inside
the crater of a volcano. It was also the site of the major
British military camp of that era.
Aden is a peninsula about three miles long joined to the
mainland by an isthmus. At the western end Steamer Point
is a good harbour; at the eastern end the Crater, a
long-extinct volcano, is where the military barracks
were first built when Aden was annexed to British India
The first Aden post office opened in the Crater in 1839.
In 1858 main Aden office was moved to Steamer Point
while the Crater office became the Aden Cantonment or
Aden Camp sub-office. Later, it was called Crater again.
Between 1871 and 1893 both Cantonment and Camp cds were
used, but after 1893 only Camp cds are known. Steamer
Point cds were used between 1858 and 1876 concurrently
with the normal Aden cds but are much rarer.
