I seem to remember reading someplace that the screw was used to lightly pressurize the case with nitrogen or something to make it more waterproof. That may be bologna, but thought I would mention it.
Non-standard s/n configuration may indicate a non-US model. It would be interesting to know what if any info is stamped on the inside of the case back.
