Looks like a late version of the Agfa Ansco Universal View. Made from 1926 to the mid-1950's. Considered one of the top view cameras in its day. Used by several photographers of note including Andel Adams, Wynn Bullock, Morely Baer and George Hurrell. It will make a great camera with that Packard shutter to use with antique glass. Good luck with the sale.
