Propeller drawings BF109 / FW190

[feuerfrei]

Hello! Guys, tell me, please, where do you get the drawings for the screws? Interesting propeller planes of World War II. Wherever I did not see manuals / drawings for sale, there were no drawings of screws. At most, this is a general silhouette. According to it, you can make a general shape, but what about the longitudinal "torsion" of the blade? After all, it cannot be done in any way in accordance with the original, if you do not have drawings of the section of the blade, divided into segments. Then where to get these drawings? The models in this game are positioned as a technique as close as possible to the original, and if this is the case, how do the developers observe the reliability of the model? Hardly on purely visual, approximate correspondence with historical photographs. How do developers create such things, what do they rely on, if the drawings of the blades, perhaps, are no longer in nature? The screws for BF109E, BF109G, BF109K-4, FW190A-8 and FW190D-9 are the most interesting. Thank you very much if someone decides to suggest answers to my questions. I don’t really hope for an answer from the developers themselves, but what if, you never know. Thank you.
