I just recently picked up a cross bar handlebar that has a factory brazed crossbar, that looks a lot like the handlebar on this bike.
Is the brace on your handlebar welded to the bar, and if you take the grip off, does it say, Made in England down at the end of the bar?
I suspected that the handlebar was a Mead, since a lot of their accessories were made in England.
Your bike, may help me confirm this.
Any help would be appreciated.
If not, I understand.
Just curious.
Fabulous bike, by the way.
