I got this shutter and am having trouble figuring out who made it. Its a double flap pneumatic shutter with geared movement. Spent the past few hours searching online and still haven't got a match.
The only markings I can find is the word "patented" faintly printed on the cylinder.
Really want to know who made it.
Let me know if you have any idea
