This mask is a variant of the MSA Ultravue, using an unusual screw thread. This mask is quite rare and was intended for use by riot police. These masks have a full visor and a head harness, with an optional oral nasal cup.

Another downside with this mask is that it does not have a 40mm NATO thread, instead using a 7/8th screw thread.

These masks were used by the riot police in the movie Terminator 2 during the raid of cyberdyne systems/skynet building as seen in the video.

This mask is not used any more and was succeeded by the MSA Millennium somewhere in the early 2000s.

Sometimes these had DEF TEC on them because MSA probably did not want there name on any of it but they seem to be more rare than the MSA versions of these masks.
