A pre World War II camera that uses 35mm film.
The Baldina has a parallax compensating viewfinder, a frame counter, and on the better lenses, unit focusing. There is no double-exposure prevention.
As for the Folding Brownie camera I don’t know where this Baldina 35mm camera came from. It would have been owned by a grand parent but its origin remains a mystery. The Baldina I have has seized up and cannot be opened.
