Alright...
I managed to get a pic of werk...100% it is the original German-written werk number, as oppsoed to something post-war.
Looks like it was a wing that was borrowed from another 109...
this is what is written inside:
Fl. 15137
zu W.Nr. 15121
Normally one was associalte the upper line with a part or component, however in this case, no such Fl.number exists in this range.
I beleive it is referring to the main werk of the aircraft itself...
In this case, and Erla built G4 Trop...which is correct, given the camouflage.
Anyone have info on either bird?
TIA
Mike
