La Spirotechnique Twin Cylinders New Old Stock
La Spirotechnique Twin Cylinders New Old Stock from the Golden Age of Diving
The La Spirotechnique twin tanks are a true representation of the golden age of scuba diving. Originally developed by the French company founded by Jacques-Yves Cousteau, these cylinders reflect the early evolution of modern underwater breathing systems.
Today, finding a set in new old stock (NOS) condition is exceptionally rare. As a result, these tanks are highly desirable among collectors, historians, and vintage diving enthusiasts.

Historical Significance
La Spirotechnique is one of the most important names in diving history. Founded in 1946 by Air Liquide, the company was responsible for producing the first commercially successful scuba regulator.
At the same time, twin-cylinder systems like these became standard for early divers. In fact, classic twin-hose regulators were commonly mounted directly onto manifolded twin tanks like this configuration.
Therefore, these tanks are not just equipment they are part of the foundation of modern scuba diving.
Key Features
Twin-Cylinder (Bibombola) Configuration
The dual-cylinder design offers several advantages. Firstly, it increases total air capacity. Secondly, it improves balance in the water. Finally, it allows for longer dive durations compared to single-cylinder setups.
Original Manifold System
This set features a period-correct crossbar manifold with dual control knobs. Unlike modern systems, this design reflects early engineering approaches to air delivery.
As a result, it provides:
- Authentic vintage functionality
- Simple mechanical operation
- Strong collector appeal
New Old Stock (NOS) Condition
One of the standout features of this set is its condition. Importantly, these tanks appear unused, making them significantly more valuable.
In addition, NOS examples:
- Preserve original paint and markings
- Retain factory configuration
- Are far rarer than used sets
Iconic Yellow Finish
The bright yellow coating is instantly recognisable. Not only does it provide visibility, but it also reflects the styling of classic French diving equipment.
Together with the black base, this creates a bold and highly collectible appearance.
Complete Harness System
The included harness and straps add further authenticity. At the time, these systems were designed for simplicity and durability.
Consequently, they provide:
- Secure mounting
- Period-correct presentation
- Enhanced display value
⚠️ Important Notes (Collector Awareness)
As with all vintage scuba cylinders:
- These tanks are primarily for collection or display
- Hydrostatic testing and inspection are required before any use
- The manifold system differs from modern DIN or yoke setups
Therefore, they should be treated as historical equipment rather than everyday dive gear.
Why These Tanks Are Highly Collectible
Direct Link to Scuba History
These tanks come from the company that helped invent modern scuba diving. Because of this, they carry significant historical weight.
