Good morning, everyone! I’ve had a few requests

Good morning, everyone!
I’ve had a few requests for pictures of the ‘unicorn’ – the Aqua-Lung that was painted blue and rebranded as JC Higgins, later re-labeled as Aqua-Lung Mistral, with a sticker placed right over the JC Higgins label.
This fascinating piece of diving history is probably one of the top 5 rarest regulators in my collection.

The White Stag Sea 1000 Lung is a vintage single-h

The White Stag Sea 1000 Lung is a vintage single-hose scuba regulator produced by White Stag, a company active in the diving equipment market during the mid-20th century. These regulators were prominent in the 1960s and 1970s and are now considered collectible items among diving enthusiasts.

Design and Features:

First Stage: The Sea Lung 1000 regulators typically feature a piston-type first stage, such as the “Deep 1,” designed for lower pressure tanks with a maximum service pressure of 2250 PSI. Notably, they have a small 3/8-inch diameter yoke screw, indicating their compatibility with lower pressure tanks.

Second Stage: The second stage often utilizes a tilt valve mechanism, a design common in regulators of that era but different from the poppet-type valves used in modern equipment. Tilt valves require a first stage equipped with a safety relief valve to operate safely. However, the Deep 1 first stage associated with this regulator may lack such a relief valve, potentially posing safety concerns. www.vintagescubagear.com.au #scuba #scubadiving #scubadive #ocean #water #sea #waves #reef #marktozer #collect #collection #museum #underwater #underwaterphotographygraphy #dive #vintage #vintagescubadiving #vintagescubaequipment #old #history #historical #historicaldivesociety #australia #usa #scubahistory #aqualung #whitestag #mares #scubapro #cressi

The Siebe Gorman Essgee Aqualung Mk II is a legend

The Siebe Gorman Essgee Aqualung Mk II is a legendary piece of diving equipment that highlights the ingenuity of mid-20th-century engineering. Produced in 1956 by Siebe Gorman & Co. Ltd., a British company with roots dating back to the early 19th century, the Mk II marked a significant step forward in the evolution of scuba diving technology. Building upon the success of its predecessor, the Essgee Aqualung Mk I, the Mk II incorporated innovative design elements that improved performance and usability. Consequently, it earned a place among the most notable regulators of its era.
