"The aero rake itself could be used for measuring air speed, angle flow, pressure (Pitot-Static probe) and even temperature", to
quote myself.
Judging by the size (diameter) of the probes and excluding other types of probes (cobra, etc) it's most likely for temperature or modified version of Boost Venturi. I'd love to know who's the vendor.
Edit: looking at the high res, there seems to be additional tunnel within the probe, and it looks like a Kiel probe.
