Brandon,

Guns that have cold blue applied to them have a distinctive odor to them from the copper sulphate... gun oil is all you should smell. If you smell anything else, be wary of cold blue touchup.

Cold blue solution doesn't cost very much and can be helpful for touching up non-historical firearms. I recommend you buy a bottle and put in on some non-important gun steel just to know what the odor smells like...

Unless I am mistaken, all genuine Navy Lugers will have large head toggle axles... Tom A will know for sure.
