Thank you all for your responses, this has been very helpful in my artwork!

In reference to your question, I take it then that the static ports are that baremetal oval-shaped area underneath the third passenger window?
If I might take this a bit further:
What is the function, then of the round baremetal port lower and a bit aft of the static ports (it's roughly under the fourth pax window)?
There is also a small pitot-appearing item on the lower sides of the nose roughly in line with the nose landing gear leg- what purpose does that serve?
Again, this doesn't affect my final artwork, but I have a bit of an obsessive habit of wanting to understand what it is I'm drawing!
