Hi guys! I have been looking around everywhere for the maker of this mask used by Robert De Niro in the 1995 movie HEAT, I have the Waingrow used Mylec mask
Seems like it's either one of those worn by Bernie Parent or Lindbergh. They made slight changes over the years to the designs of the same basic model of mask, altering vent hole placement, eyehole shape, and even minorly altering the overall shape of the mask.
