In the early 1920s, the Frenchman Alain Terme acquired a Neufeldt and Kuhnke suit for undertaking attempts to locate several shipwrecks with valuable cargoes. One of them was the Egypt. In 1924 the famous Italian company SO.RI.MA. (Società Ricuperi Marittima) was founded, more or less with the same objective. Two years later Terme joined forces with SORIMA and transferred the armoured diving suit to them.

The initiative to simplify the armoured suit to increase its practicality and functionality was created by SORIMA. This company had employed the Neufeldt and Kuhnke suits of differing types (second and third generation) for recovering valuable cargoes from several shipwrecks in deep water. (e.g. Washington, Elizabethville, Egypt) SORIMA acquired the Italian rights to the ADS suit. The major modifications included: (1) The total amount of ball and socket joints was reduced to six to further limit potential leakage, (2) The entry opening (don – doff hatch) was moved to the top of the upper torso so the trunk could be cast as one solid structure, (3) The buoyancy tank was moved to a lower level on the trunk. The last measure gave the suit a more natural centre of gravity while submerged and had the added benefit that the suit entry opening floated higher above the water when not submerged. Also, in a latter phase, the straight elbows were replaced by curved and lighter ones, an innovation added by Robert Galeazzi.
