Fig. 15 The Wild B9 Aviograph Small Scale Plotter is a mechanical plotter with the rigorous geometrical solution 
for plotting from super wide angle photographs. 
  
Fig. 16 The free-hand movement of the drawing point, the rigorous geometrical solution of the plotter, and the 
orthogonal observing system with 8x magnification, are the significant features of the new small plotters. 
All controls are within easy reach from the operator's chair.
