          Historical wind tunnel constructed by R.A. Bagnold (c. 1935) out of wood and glass. The wind tunnel was an open circulation, suction-type
          tunnel, with overall length of 9.14 m with a cross-section of 0.30 m x 0.30 m. The tunnel was housed at the Hydraulics Laboratory of 
          Imperial College, London in the 1930s.
