My two Lugers
 

I snapped these with my new point & shoot camera (my excuse for the picture quality).

The first is a mismatched gun with a Bohler Stahl barrel and some sort of crest on the toggle

This one is a well worn 1937 S/42. The numbers I can see on the gun match, but the magazine is 1944.

The "some sort of crest" is from a 1908 Bulgarian contract Luger. Sometime back, I think it was in the late 1960's, a lot of Bulgarian Lugers were imported. Many were in less than pristine condition (collectors would jump on them now). Some of the better ones were sold intact, but a lot of them were parted out and now show up in bits and pieces, yours is one of them.

How's the safety on the long barrel marked?

The safety markings on both guns are the same: Gesichert.
