Hi,
Can somebody explain me (explain us) the difference or the reason why these two different machines wear the same Stkz.
One TL+DR known photo in Jet & Prop 3/97, p.8, photo; Menke, SKZ list (??? I suppose not having the original source) A Regensburg machine
One TL+DR machine from eBay auction, a WNF machine.

What the hell did happen here?

Thanks in advance.
Regards, Franck.
