The listing provided is organized using the typology I have created.
A tremendous amount of work gathering examples of the different marks was led by Dennis Firth support by a number of other members of the Bechuanalands and Botswana Society.
At this point, the listing is a work in progress and is simply re-ordering of the illustrations that he collated and presented in Runner Post issues 63, 66 to 72, 75 and 80. it uses the format developed by Mr. Firth for the data describing the marks. I will be updating this listing with additional illustrations from my collection. This listing I have created focuses on Botswana and does not include the official free marks of Bechuanaland.
