I suspect that was mislabeled by the original seller (i.e., the store in Rochester that's mentioned by the seller of that lot). It doesn't look like a Tachihara; it looks more like a late-model Nagaoka. The Tachihara name is widely known, so many sellers just call any lightweight wood-field camera a Tachihara if there's no label on the camera and they don't have any information as to its origin.
I have a 4x5 camera that's very similar to the one shown in that auction, except that it has Graflok sliders on the back. Mine doesn't have a brand label on it either; it's possible that more than one vendor sold cameras with this design.
It may well be complete and ready to use when it arrives.
One thing to watch out for is that earlier versions of some of these Japanese wood-field cameras used proprietary wooden lensboards rather than Technika boards. I have an early Nagaoka 5x7 that uses odd-size wooden boards; later ones take Technika boards. The cameras are perfectly usable - it just means you might have to have lensboards made rather than buying off the shelf.
