This one is Dirty Harry approved for sure. S&W 500 Mag. Sitting below it is a Ruger SP101 357 with a 2" barrel.

 

Mine is the real deal.. same year/barrel length/finish that that Dirty Motha-Effing Harry used.
But that is a fine collection you got there!

 

The blueing spots are where rust started to form and then the gun was oiled to remove it.
You should put your guns in an oily rag if you are going to store it in the foam container, unless the container is in a climate controled environment.
That's what i do with all my blued guns. the stainless ones are not an issue.
i had the same problem years ago and tried to warranty the gun.
Blueing is not the best protection for steel,, but it is pretty!!!!
