The Schneider CA1 didn't use the classical Holt suspension as the St-Chamond (and A7V) did. The suspension was somewhat similar to that on the later FT.
Attached are a couple of images of the Schneider at Saumur showing the springs and what looks like a fairly substantial framework supporting the caps
for the springs. Anyone have any good images of this, or a decent drawing of how this was organised?
