Blair Camera Co. was located at
471 Tremont St., Boston Massachusetts,
hence the name of this model.
It sports a B.O. & Co. lens.
The folding base is made rigid
by a sliding metal plate. The back is held in
by two large springs, unique amongst even Blair models. The
plate-holder for the Tremont is square, with the extra space
taken up by large, weight-reducing oval depressions (see upper example).
The inside of the ground glass back has identical depressions (see lower
example).
