Hello,
I have a piece of a verticle stab section from a Bf109 G6 I think? model with the tall tail , that I believe was made in the Erla factory early 1944 best I can findout so far.  The section is the top rudder fin cap that carried the wknr 413581  painted on it.  
I would like to know more about the aircraft that this piece belonged to. Such as what unit it was assigned to , maybe what country did it see action in after it left the factory , if any , who were possible pilots ?  Anything would be neat to know.  I build RC model planes.  I'm planning a 109 G model next , I just completed a 1/6 Bf109 E3  .   
If I could find out more about the plane , it would be fun to try and do an exact paint scheme on the G model,  which will be appox 1/5 scale. 
Thank you ,
Fred P.
