Oh dear! Boys were boys and girls were girls. Those in between were either actors or artists and one didn't talk about them which is more than likely how they liked it as they went on to great things. Think of the great actors of the last century, when most were aware of their orientation and didn't really care about it. Those who were apprehended, from Oscar Wilde onwards seemed eventually be accepted for their works and not their indiscreet sex life.
Engines, ships, cars and other male toys were always referred to as 'she' as possibly they were held in as high regard as their mothers, girl friends or wives. The Rev Awdrey was brought up with all this, hence his writings, which have been highly appreciated for years and which will no doubt continue to be appreciated long into the future.
