Very nice work on the interior. Personally I wouldn't worry about the prop unless you have a photo of the aircraft you are modelling and can prove what type of prop it had. They didn't stick to one type and they were also consumable items that would be changed. But if you want to do more tiny carving, don't let me stop you......
