That's an Atom drum brake. These were common for tandems in the '70s. (The ad says: "marked Brevete SGDG" which means "patented inc.")
These were not wonderful brakes, but not terrible either.
However I very strongly advise against using a single lever to control two brakes. Best way to use a drum brake on a tantrum is as a "drag brake" with some sort of derailer shift lever.
See my article on Tandem Brakes for details on this:
