JonE - Greetings. The Aussie one-piece screens came in two heights and were made here. Re the air - they open out at the bottom & the top!. The pillars were thick, solid brass, (including the lamp bracket at the base on the early versions), and quite heavy, unlike the semi-circular, thin Longbridge ones. The swivel point was about 2/3s up each pillar and regulated by a large wing nut each side.. Cheers, Bill in Oz
