The EK2 is real.
The PLM is IMO a fake. That particular style of Eagle
with the very distinctive tail feathers is attributed to
the firm of "Rothe & Neffe". Originals from this maker
IMO would not be stamped with a Godet maker's mark.
Godet never made PLMs with that style Eagle.
Now for the last Ek1 you posted.
Thank you for that one because the seller posted some
real nice pictures for me to add to my FAKES file. PLUS,
you might notice that this cross is exactly the same as
the first Ek1 that you posted earlier in this thread.
Any time you see a cross with the overly large crown
and the closed 4, a red flag should go up. As I said earlier,
there are known good examples of these but most that are
seen (especially on ebay) are fakes. and they are GOOD
fakes . Fooling a lot of people even experienced collectors.
---This one was easy to spot because of the "K" makers mark.
ALSO if you look at his other listings, He has the same cross
only with slightly different hardware with a "WS" makers mark
on it. That cross is ABSOLUTELY not a Wagner and Sohn cross.
NOT EVEN CLOSE.
