As you might have guessed I am interested in the Franco-Prussian war at the moment and I am trawling the web looking for information - mainly pictorial - so I can get to grips with this clash of arms. This site has some excellent illustrations from all manner of sources, and is worth a look even if you don't speak French. What I am wondering is to what extent French equipment of 1870 is the same for 1914 - I have a feeling that although it looks the same it's all different.
