The recommendation is to follow the movements of the line; trying to "rewrite" the letters in your mind. The name certainly ends with "...dy" or "...."wy". First letter typically "t"'s are written this way and the hieroglyph in the middle: is there anythingbut an "x" which can be written this way? "V" during heavy swell? In signatures often an abbreviated first name,academic grade or rank can be included. It could also be a "Namenskürzel", an abbreviated signature if the author had to sign some hundred invitations. Mine would be "QxBP" or "QXBruPi".
