STAR TREK: DS9 “STARFLEET BREATHING DEVICE LOT” FROM “NOR THE BATTLE TO THE STRONG” & “LOOKING FOR PAR'MACH IN ALL THE WRONG PLACES”

A Starfleet breathing device lot in the style used at the Federation hospital on Ajilon Prime in the Star Trek: Deep Space Nine episode “Nor the Battle to the Strong” and the one tentatively tested by “Miles O'Brien” (Colm Meany) in the episode, “Looking for Par’Mach in All the Wrong Places”. There are two clear plastic masks with black and gold applications and metal spring tubes attached to a resin cylinder in the front. One also has an additional extended piece with more spring tubes and one red and one green LED light. There is a switch on the back but the electronics are untested since the battery cavity is difficult to access. The more complete mask measures approx. 6 ½ x 4 ¼ x 2 ½ inches.
