Unidentified Real Item: MSA GALLET ACH MICH TC2000 (Details Unknown)

Unidentified Real MSA GALLET Shield Helmet ACH MICH tc2000 US Military Riot Police Bulletproof Visor SWAT Riot Control

I believe this is a real item, not a replica, but the details are unknown. The helmet type is likely tc2000.

The visor was manufactured in December 2003.
The helmet was manufactured in January 2004?

Size is unknown, but:
Length from the top of the visor to the back of the head: approximately 30cm
Inside the helmet, front to back (forehead to back of head): approximately 25cm, inside ear to ear: approximately 23cm, inside top to bottom: approximately 16cm
These are approximate measurements.

The nut on the visor attachment was loose, and the black part was dangling, so I put it back in its original position and tightened it. It may appear to be off in other images, but it is not broken, so please understand.

Both the helmet and visor have scratches. There is rust on the metal parts. There is no damage that impairs functionality.

Everything in the images is included.

Thank you.
