Some questions about damaged airframe and reparation centers...

[olefebvre]

While going through the 109 production data i have collected so far i have noticed something odd.

So here is my question:
An aircraft getting to a reparation center with an usable fuselage would be repaired and will keep its WkNr, do you agree?

Now if the same a/c got his fuse so damaged that it can't be repaired, it still can provide some spares (lightly or undamaged parts), what will become of those spares ? Would it be possible that they were mated to new fuselage and not appearing on the production list of the fuse manufacturer ?

To sum up would it be possible that reparation centers were attributed some WkNr blocks for their own use ?

Thanks in advance for your help.
