Bonjour Pierre-Michel,

I don't think there was anything unusual. The film doesn't show each of the eight bolts being fastened, nor the castellated nuts or locking wire fitted through the holes in each bolt. I don't believe the British had a quick release and fastening hub. Lucien Chauvière developed one to the prototype stage before WW1. Do you have any information on it? Rupp in Germany developed his successful one with a central nut, around 1917 and his company continued well into WW2. The thought always occurs that Rupp might have worked for the German Branch of Chauvière's Integral company, seen details of their quick-release mechanism and developed it himself to successful widespread use.

Avec le Respect,

Bob Gardner
