Welcome to the forum.

You'll probably have to remove the recoil spring before re-inserting the pin unless you can re-align the lever with a conical pin first. It's likely under a fair amount of pressure which will interfere with getting the holes aligned.

A special tool is generally used for pushing the recoil spring alignment rod up and unhooking it from the lever. It may be more difficult since the lever has no fulcrum to rotate on.

Note that your Luger has been refinished, and should be marketed as such. The magazine and sear safeties are also intact on this pistol, which is unusual.
