These were factory changes to the 41 engines and I believe correct for a 40 because a later bulletin issued during the war reminded about proper storage and apparently changed their mind about the horizontal vent pipe being enough on 40 engines. The oil tube changes was suggested on 356 engine exhibiting symptoms of rusting and sticking valves and that was how they were built postwar.

This includes the taller oil filler tube so that the cap would cap would catch more air from the fan, a change in the oil filler cap to a larger, flatter shape with a large slit on the forward side to catch more air, and later the addition of a tube to direct the air from the fan more forcefully and directly to the slit in the cap. I would imagine a diligent dealer making these upgrades to the '40 engine when it was brought in for servicing.
