Hi all. As you know that at the moment I'm trying to restore my vintage roadbike, and have really struggled to find out its origins. Its thanks to all of you, for supplying me with links and photos, that I have got half way there ! 😊
Whilst stripping the bike down ready for a respray, I de-greased the crankset and measured up the ball bearings etc for new replacements. Upon wire wheeling the crank shaft , low and behold, bang in the centre of the shaft were the letters Windsor!
I've checked the Windsor back catalogue, but cannot find one of there frames I.e comp, pro etc etc which has nervex style lugging. Nor can I find any correlation with the Winchester head badge?
So...I'm slowly gaining snippets of info, but could still do with some assistance.

Agree. That said, "Windsor" would be the manufacturer of the bottom bracket spindle; nothing to do with the bike manufacturer of the same name. With the possible exception of, e.g., Lambert/Viscount, no bike manufacturers use self-named parts in bottom brackets.

Sorry guys, I didn't know ?
I'll continue on the op
