- Janne,

Your map graphic appears to be in the Winkel Tripel map projection. I would 
also suggest that it is using Oswald Winkel's original selection of 50.46667 
degrees as the Special Parallel.

Note that by the 1950s John Bartholomew was using a special parallel of 40 
degrees for his version of the Tripel, giving his graphic a more flattened 
appearance in the Y direction.
