In this paper, we study on finite projective Hjelmslev planes M(Z q) coordinatized by Hjelmslev ring Z q (where prime power q = p k). We obtain finite hyperbolic Klingenberg planes from these planes under certain conditions. Also, we give a combinatorical result on M(Z q), related by deleting a line from lines in same neighbour.
