For a research-project I'm doing on a night-fighter model I want to build I have a more general question regarding kill-marks on the rudders of a typical Luftwaffe plane.
Suppose a pilot serves with a random ZG and achieves one or two victories. After a while this ZG is renamed and turned into a NJG. This same pilot goes on to serve with this newly renamed/formed NJG. Would the rudder of his plane also carry the victories achieved while he was flying for the ZG or just the ones he achieved while flying for the NJG (starting with a clean sheet so to say from the moment the NJG came into being) Any rules/procedures/protocols known that deal with these kind of things? Or perhaps even a rule-of-thumb that these kind of things come with the pilot wherever he served, rather then stay with a particular unit.
As details on the plane I want to do appear to be quite sketchy (at this point anyway, although I don't know what might yet be unveiled) I'm trying to make a kind of educated guess when it comes down to filling in certain blank spots.
