Looking good. It is quite interesting that there isn't much in the way of Brits for this period. I guess the earlier Martini-Henry era is seen as the gold standard, and this one is left out in the cold a little, despite there being some very famous encounters (also I guess it doesn't help that you can pretty much get away with using figures from the earlier period if you aren't too picky). I seem to recall Studio Miniatures did a range, but I'm not sure what happened to them. There may be others, but they don't seem to have hit the big time to a degree that I can actually remember them.
I have a few Boers from that old Foundry range, but I don't have the MG set, sadly.
By the way, it's Maxim gun, not maximum gun. Named for Hiram Maxim, the American inventor of it.
