Good Evening / Morning Ladies and Gentlemen
I have come across a gentleman who has said I can have first pick of several Western Electric No 1-A Flying Helmets - actually he has 10.....
The primary question is: each has a hole through the top cinch strap. I've seen this before, but have no idea what the significance is - if any - I have not been able to find any information on this interweb thingy, nor in books.
Only two have labels and they state: Western Electric No 1-A and the size, as opposed to the previous and Patent Pending - so I assume they are slightly later models - again no luck with the research.
Has anyone got any idea about: 1. dating them; 2. the significance of the hole?
...well you get the picture.
