ABSTRACT:
  We characterize natural transformation between Weil Bundles 
that are endowed with a canonical affine structure and show 
several cases. Those transformations are often passed down 
to Jet Spaces, and we characterize the cases in which the affine 
structure is also passed down. We prove that the classical 
situation is an example and give some practical generalization.

Key Words:  Jet, Weil Bundle, Affine Structure
