Hi Alan
thanks for the welcome.
Confession time.........I didn't do the restoration.
I was looking for a Commando to rebuild and in the time I was looking saw this one pop up for sale (at a huge price). I spent over 12 months looking for a Commando that Icould fix up to the spec. I wanted and had tallied the $$$ as to what it was going to cost me all up. In the meantime the price of this bike came down below what I had figured I would have to spend all up to build what I wanted, and it pretty much had all the mods on it that I would have incorporated into my build. So I bought it and I reckon I saved money by doing that. I'm still having fun fettling it and trying to iron out some little niggles (part of Brit bike ownership as you know).
So the front brake caliper as I understand it from the PO is actually a Lockheed replica......the disk is a Norvil product (so far OK

).
Cheers
Norm
