| Abstract: | Let X be an affine surface admitting a unique affine ruling and a
-action. Assume that the ruling has a unique degenerate fibre and that this fibre is irreducible. In this paper we give a
short proof of the following result of Miyanishi and Masuda: the universal covering of X is a hypersurface in the affine 3-space given by the equation xmy = zd − 1, where m > 1.
