Surefire 6px matching serial numbers?

Looks like the red and black packaging has made a return along with serial/production numbers on the body instead of the head.

The batteries in the one I opened are 4-2018. I suspect that since it was the cyber monday deal that they were old stock. I posted another pic (bigger) in an earlier thread just now.

Just realized that its easier to take and use a photo immediately instead of trying to add an existing photo.

Or what the SF guy said, "production number"....

Honestly, this makes very little sense to me :shrug:

Not a model number, not a patent number, not a batch number, not a date code ... and not a (sorta by definition, unique) serial number

I seem to remember that one of the main purposes of the CE and FC certifications for sales was a unique and different serial number for Gov/Mil/LE contract
sales. Maybe that's changed.
