Springwood figures first appeared in 1972 as a single set of 24 figures made up of 6 each of French, British, Russian and Prussian line infantry (top row), there were no officers, musicians, etc. They were made in hard plastic (polystyrene).
This was followed by an upgraded version of the first set slightly higher with better detail plus two more sets covering the other major troop types.
Top row - originals British Line (as Portuguese legion), French line, Russian Line, Prussian Line,
Second row - second range - British Line, French Line (LHS with plume removed as fusiliers), Russian Line, Prussian Line (as Reserve Infantry).
Third row - second range - Austrian Grenadier, French Grenadier, Highlander, Brunswick Legion
Bottom row - second range - Bavarian Line, British Light (as Portuguese Line), Austrian Line, Landwehr (wearing clogs).
I'm still looking for a few more to fill in some gaps in my armies so please contact me if you have some to sell/swap. I've still got left over British line(first range) and Highlanders.
