Here is one of my favorite Kragicon pictures: Boer General Tobias Smuts with Steyr made Krag, believed to be serial #124. On a South African site there was mention of the first order of for Steyr Krags being for only 100 rifles and 25,000 rounds of 6.5mm ammunition. The few surviving rifles in SA ran from #69 to #165. There are also other rifles, apparently from later SA procurements in the 3, 4, and 5,000 range.
I believe there is a known ZAR marked Krag that was confiscated in Ireland, during the Rebellion.
To add to the confusion, the Norwegianicon Army apparently had Steyr made Krags numbered from #1 to #20,000.
