I saw that one Rohan. Would jump if I knew what it norton it was from.!!
I'm fairly sure that would have to be late model 750 drum brake.
(those patches of weld look ugly, but the $price is right)
But I've not even seen one before - I've only played with 850s.
The 850 ones have ANG underneath them, and are for the disk brake.
As
GP sez, the rake is a bit different - for disk brake use.the fork tubes
are angled slightly backwards in them (!!)
