Natural transformations of the Weil functor $$T^ A$$ of A-velocities [I. Kolař, Commentat. Math. Univ. Carol. 27, 723-729 (1986; Zbl 0603.58001)] into an arbitrary bundle functor F are characterized. In the case where F is a linear bundle functor, the author deduces that the dimension of the vector space of all natural transformations of $$T^ A$$ into F is finite and is less than or equal to $$\dim (F_ 0{\mathbb{R}}^ k)$$. The spaces of all natural transformations of Weil functors into linear functors of higher order tangent bundles are determined.
