The Jack is an easy fix, just fill the void with (in my case)"Squadron White Putty"and let it dry then sand it flat and paint.
As to the starting handle, there were as far as I know two types, the later one was a two piece component which was stored just in front of the left hand engine grille (viewed from the front) near the radio aerial, the early one was clipped on the rear panel to the side of the towing pin. Hope that helps.
