Their WotR range only goes up to Stoke Field, but their Italian Wars range can extend past 1500. Both of the Twins are into Tudor re-enactment and have been photographed in early Henry VIII "uniform" (the short-sleeved white smock with green trim and red cross), so I wouldn't rule out later figures for England/Scotland/Ireland.
Nice pike block, by the way. I never think they look right unless they have at least three ranks in them!
