This has been discussed a few updates back and some people came up with reliable references describing the situation. It turned out that it's accurate as hurricanes had 2-3 different spinner arrangements, sometimes depending on the type of propeller used.
If i remember correctly, IL-2 models one kind of spinner while the screenshots we've seen of SoW tend to model the other one.
Bottom line is that both arrangements are accurate, plus the missing spinner design could perhaps be added at a later date in a patch.
If we wanted to get really pedantic about it i'm sure someone could come up with reliable data from the 40s, giving us the statistics about what percentage of Hurricanes used each spinner type so that the sim could model them in such a fashion. For example when the player's squadron spawns upon mission start, we could have 60% of the Hurricanes sporting one type of spinner and the other 40% having the other one.
To be honest, i think it's a modest detailing issue and since the type of spinner modelled in SoW was in fact used at the time and is not wrong historically speaking, i tend to consider the addition of the second spinner type a cosmetic detail that can be added at a later date.
Mind you i'm not trying to be antagonistic here. I'm just trying to say that while your observation is correct, it's not exclusive as the type of spinner we've seen in SoW screenshots was in fact also used during the battle of Britain. Just trying to be careful with my wording here, as i'm just back home from a night out with friends and my system is "fueled" by a few vodkas and various other beverages. I hope this helps, cheers
