Any other good sources of deep wrecks prior to the 1970s?The "bathysphere" is specifically the one used by Barton and Beebe, so it was not used for salvage. However, one atmosphere observation bells have been used on a number of famous gold salvage jobs including the SS Egypt in 1922 and the RMS Niagara in 1940. These bells were more cylindrical with the one person standing and looking out through viewports all around the upper portion.
@happy-diver sent me a vintage copy of GOLD FROM THE SEA. The Epic Story of the "Niagara's" Bullion. by James Taylor which is much appreciated. It described the salvage in great detail.
The Italian Galeazzi Butoscopic Turret was still being sold in the 1960.

They were similar to the bells used on the Egypt and Niagara. Here is an image from the Undersea Industry catalog, a short-lived division of Scubapro.

Another bell was the McCann Rescue Chamber used to rescue men from the sunken USS Squalus (SS-192) submarine. We were still training on the McCann bell in the 1970s. The DSRVs obsoleted them but the Navy still had them onboard their newest generations ASRs (Auxiliary Submarine Rescue vessel) well into the early 1990s.

I'm interested in the early explorations and salvage of wrecks in the late 19th to the mid 20th century.A lot of gold was salvaged from the SS Laurentic by Royal Navy Divers. A more recent salvage was $220 Million in gold bullion Recovered from HMS Edinburgh in 1981.
Are you only interested in gold salvage? There are some pretty amazing stories about the salvage of submarines.
How were wrecks found before the invention of sonar?
How was deep operations before helium conducted?
The search and investigation into the USS Scorpion sinking is absolutely fascinating in the way that it was the first true abyssal exploration of a man made object and the incredible challenges that persist to this day on it.
Thank you for the definition. I had heard of bathyscaphes, but I was confused about how they differed from bathyspheres and submersibles. It seems in some ways like the differences between a dirigible, a zeppelin, and a blimp; that is, all similar in concept, but using different buoyancy techniques.The bathyscaphe concept was developed by Professor August Piccard, a Swiss physicist. Piccard set a world altitude record in 1931 at 15,781m/51,775', 9.806 miles in a hydrogen balloon with a pressurized "gondola". Bathyscaphes were analogous to his hydrogen balloon except it used aviation gasoline for buoyancy and a MUCH higher-pressure sphere for the manned “gondola” or cabin suspended below. Air ballast was vented at the surface to descent and iron shot was released to ascend.
I noticed what looked like the JIM suit, or something similar, in the background of that picture.The Italian Galeazzi Butoscopic Turret was still being sold in the 1960.
