In Walsten Air's service, it was fitted with Bristol 7850 floats as used on the Beech 18, and this required the removal of its ventral fin and the fitting of two vertical fins on the horizontal stabiliser to provide greater stability with these larger floats. Earlier in its career it had on two separate occasions broken through ice on landing and become almost totally submerged in the lakes, resulting fortunately in recovery and major rebuild over time. Two months after this photo was taken, it crashed on touchdown at Salvesen Lake, Ontario with the tragic loss of all on board.
