The 2915 did indeed come with a number of case backs, I have one with a very clear hippocampus and the script (2915-1) but have also seen them without. They exist in both executions and both perfectly legitimate.
Here is my 2915, it has also had service replacement hands and bezel aged (also slightly later circa 1959 tropical brown dial) this is one of the few which exist with extracts, 2915-1 which was delivered in 1959 to Switzerland
Btw my 2915-1 also has an extract and was 'created' in 1959 as does a another that I know of, so I wonder if the few -1 with extracts all came from that later period of manufacture? Could be.
