If I am not mistaken, they are sculpted by the incomparable Holger Ericsson. The thickness of the bases suggests SAE to me, as do the paint-jobs.
The subject matter is another thing altogether.
Up until now, I had thought SAE had produced ACW, AWI and WW2 toy soldiers only. These look to me very much like FPW Prussian dragoons. Equally interestingly, the mounted figure in dark blue seems to be riding a limber horse and quite frankly, his helmet speaks to me of the British army of the last quarter of the 19th Century.
Was there an SAE Franco-Prussian War Range at some time? One day will I turn up a forgotten SAE gun and team?
