Is this an Luger?

[Rufes]

Hello!

Last week i found with magnetfishing a frame of a Luger. (unfortunately missing some things) On a spot that I did not expect.



After a week in the Vinegar some detail came above



Today started with some cleaning.


Unfortunately, the spring has gone in some parts

But I started to doubt. Some parts I have not seen on other photos on the Internet of the Luger (metal coulored, like gold cube) And there is no hole or something where a trigger should supposed to be.





So now my question. Is it a real or a replica Luger P08? And if this is real, were shoud the trigger been mounted? Because there isnt a hole or something. I am now very curious.

Thanks allot!
