Small errors in the manual?
I think there are some errors in the in the MSFS Turbo Arrow manual.
On pages 19, 56 & 59, the screenshots of the oil pressure gauge seem to be that of the non-turbo version.
Also, in the "Shutdown" section of the example flight (which uses the Turbo Arrow IV), the manual says to "switch off the navigation and rotating beacon lights"; however, the Turbo Arrow IV has no rotating beacon. You point out this difference between the turbo versions on page 22, but it might also be worth pointing it out in the example flight on pages 55 ("Starting the engine") & 70 ("Shutdown").
I know these are minor points but since I noticed them, I thought I'd point them out.
