Probably not a lot of help, but I have one (not for sale though)

It's white (could be mdf or melamine), can't find a brand name on it though,

It has the top shelf (for nappy mat), a drawer underneath that, then another two shelves. I purchased it second hand, a couple of years ago so obviously they're out there somewhere. I have also seen wooden ones very similar.

Have you tried the online baby supply stores?
