Looks a lot like my Tashihara Hope. I think they build those for mutiple customers, Calumet one of those. Guod luck with sale. Can't go wrong with this kind of cameras. LIght and plenty of movements for most situations.
The big hole at the base is a cool idea, in order to accommodate a small lens (135/150mm) installed while folding down. The tripod socket is offset a bit, but it maybe still ok.
My Tachihara Hope is too pretty to attempt such a modification though.
