The typology is a Adobe Acrobat (.pdf) file based on an examination
of over 1,200 meter marks. If you you not have the Adobe Reader,

The typology is based on the design of the meter prints, as the
simplest means of classification. Using the type of machine as a
basis of differentiation was attempted and abandoned due to difficulties
in identifying which machines made which marks and the realization
that multiple makes of machines made the same mark. It was not possible
to adopt the popular practice of identifying meter mark types by
meter licence prefixes, which
in other countries often denote the manufacturer of the machine.
In Botswana, after limited early attempts to assign prefixes based
on machine types, all meter licences are prefixed with an 'R' giving
no indication of the manufacturer or the machine type.
The typology classifies the marks into groups, which are then divided
into types. Types are further sub-divided into varieties. The classification
of types is futher described in the introduction.
