I did not remove the turret because I had no need to get inside behind it. I did not want to introduce any faults.
I expect the URSA main body under the turret will be the same. In the back of the turret there will be separate sockets or plugs which match sockets or plugs in the camera body, maybe Lemo type, like the SI2K which has a docking body for the camera module. On the PL turret, there is probably a blank hole or depression where the lens control plug/socket would be on the EF-Mount turret.
I imagine that at some point BM may have thought of making the turret detachable to be used as a remote camera head on cables like the SI2K P+S recorder unit and the SI2K mini.
