Portland Loo
By mid 2014, there were 7 Portland Loos between The Fields Park and the South Park Blocks. Marketing for the restroom was then transferred from the city to Madden Fabrication. By February 2016, there were 21 restrooms installed in eight U.S. states and British Columbia.
Ted Eldred
In 1960 the French firm L'Air Liquide, which owned U.S. Divers Corp., and the patent to the Aqua-Lung, bought Eldred out, under threat of flooding his market with their products. The Porpoise continued to be marketed under the name Australian Divers Spiro Pty. Ltd. Eldred worked for them for a time, but eventually left diving behind, discouraged by this experience. Later Australian Divers Spiro ceased production of all of the Porpoise models, but had to continue to supply the RAN because of an existing contract. The last Porpoise sold was the RAN variation of the Porpoise Universal in 1976. About 12,000 Porpoise units were produced, but only a few dozen of all models are known to exist today. The more common French Aqua Lung was produced in far larger numbers, with 12,000 being made in a single month. Today the French design is considered obsolete, while the Australian design is made and used world wide.
