See the re-posting concerning captured Boer flags at the RNSWL museum. Given the passage of time, THAT is the condition in which I would expect to see an original Boer flag these days.
Sadly, the maker of the Z.A.R. and O.V.S. flags has branched out, and is now fabricating C.I.V. pieces ....
Tell-tale features include the fictitious ink stamps on the headers and the use of thread that remains white despite the discolouration / tea-staining of the fabric panels (possibly due to the use of poly cotton thread). Also, the white fields tend to have very heavy creasing, which often doesn't match that of the adjoining panels.
