I was in Cebu City a few days ago and there I found this Matchbox S Cargo. (Its bottom lists its name as Snail Truck.) Weird-looking Matchbox models are pretty hard to find. The name (a pun on escargot, the French word for snail) is not new; it was used by Nissan in 1989 for their “small cargo” van.
It seems that when it was first released in 2004, there were two versions: the USA version with a toy number of C4538, and an international version with a toy number of H5807. The one I got is the USA version.
