I was looking for info on the 80W lightweight charging set via Google with Enfield Cycle Company as part of the search term and came across the following link:

Not sure if this is widely known about, but it has limited details and photos of Royal Enfield war production, with some details of Flying Flea and WD/CO bike production. Thought it might be of interest if you haven't seen it before.
