Schneider CA1 in 1:100 scale, which comes in a pack of two from Battlefront. It's mostly a very simple model to build; just six pieces — the hull, two interchangeable running gear units, two machine guns, and an extension for the girder on the nose.
This last is the problematic bit. For some reason, Battlefront thought it would be a good idea to provide this as an extension to the hull moulding, to be held on by glue with the tiniest, most fragile contact point possible at its base. It would last about five minutes under normal wargame conditions. I replaced that with a piece of plastic angle strip, set into a channel carved out where the original moulded bottom part of the girder was. It's sturdier, and it looks better too, and took about five minutes.
The Hotchkiss machine-guns on this one were a bit misaligned in the mould, but they'll do. They're much better on the other model in the box. They're quite vulnerable to handling damage, but I don't know that there's a great deal that I can do about that.
