Street Letter box facilities existed in four Jamaican towns; Kingston, Montego Bay, Port Antonio and Savannah-la-Mar. The first three of these towns had distinctive handstamps, bearing the lettering "STREET LETTER BOX" for letters so posted.
The earliest die,established in 1889 and used in Kingston, was a simple single-line diamond with "STREET LETTER BOX JAMAICA" in three lines:
Subsequently, datestamps containing this same lettering came into use in Kingston (5 types), Montego Bay (3 types) and Port Antonio (3 types). While Savannah-la-Mar had street letter boxes, no specific cancellations are known for this town.
The descriptions of the Kingston cancellations are based on the monograph by Thomas Foster (But see also: Swarbrick).
Street Letter Box Cancels
Kingston Type
SLB1 The first mark was a
metal "TRD", which had a single-lined diamond frame with
23mm sides enclosing the legend "STREET LETTER BOX /
JAMAICA" in three lines of slightly seriffed capital letters
21mm high. Undated, struck in black ink and, in its last
year of use, battered and misshapen, it was intended to be
struck only on the envelope or wrapper, leaving the
adhesives to be cancelled by one of the Kingston date
stamps. In practice this rarely occurred. Although uncommon
on cover, contemporary stamps can very often be found
bearing parts of this postmark and it is not so rare as is
often stated Kingston Type
SLB2 Type SLB2 is a postmark
of the Double Circle classification, which has the normal
double-circle format with a diameter of 26mm and about 1mm
between the circles. The date is in two unit plugs reading
"month-day" and "year" in two lines with an index figure and
letter above it, all in sans-serif type 2 mm high. The
legend at the top reads STREET LETTER BOX and at the bottom
KINGSTON JAMAICA in sans-serif caps 3 mm high, with small
dots separating the two legends Kingston Type
SLB3 Type SLB3 closely
resembles Type SLB2a in the size of the various units and in
overall diameter, but it has dots at the sides and 11Ž2 mm
between the circles, as in Type SLB2. The index combination
above the date is replaced by a single central index letter
ranging from A-Z; it is only known struck in black. The
author considers that only a single dater of this type
existed, and it would appear to have been issued at a
later-date than the previous two types Kingston Type
SLB4 Type SLB4 is another
double-circle date stamp of 28mm diameter, with 11Ž2 mm
between the circles. It has the legend STREET LETTER BOX
KINGSTON around the top and JAMAICA at the bottom in small
square capitals about 2 mm high; it is without separating
dots at the sides.There is an index combination above the
date in tall upright 3mm units, the figure being heavily
seriffed. Six identical daters of this type were issued
distinguished by the fixed figures 1 - 6, the index letters
ranging from A - Z. These stamps are, found in either black
or blue Kingston Type
SLB5 Type SLB5 is very similar
in format to SLB4, but with an overall diameter of 271Ž2 mm
and with 1 mm between the circles. The lettering is 21Ž2 mm
high, tall and slender, but the date units and index
combinations are exactly as in Type SLB4. There are,
however, dots at either side.In all probability a set of
these daters was issued, but only one has been recorded,
struck in black. The illustration M18 in 'Nicholson' is
incorrect, and should be disregarded Kingston Type
SLB6 The next dater closely
resembles SLB4 with the same diameter and distance between
the circles. The lettering is similar to that of SLB5 but is
narrower and closer together, with a period after the word
"BOX" but without the dots at the sides. A single central
index letter above the date ranges from A-Z,, but this and
the date are in smaller squarer type 21Ž2mm high Probably
only one stamp of this type existed, and it is known, only
in black Montego Bay Type
