What in the world! Plz help ID Luger part

[Edward Tinker]

I am building up a shooter and came across a couple of parts that I found odd.

First, what is this safety lever for?

I was trying to put it on and noticed it did not have a detent (wrong word) but pin to hold the safety lever? Its not broken, its just not there and the end is squared?

Then I went to put on a mag catch and it's BENT?

How does a mag safety get bent except on purpose??
