New York Police with Lugers

[alanint]

I think that the ".45 Luger" is actually an optical illusion where you are seeing the wear on the very edge of the muzzle ring highlighted by the flash, making the muzzle appear larger than it is.
The other object appears to be some sort of leather case with a cover flap and stitched on rings to attach the case to other gear. It is being held upside down, with the flap in the lower right hand side of the object just past the metal ring.
