I recieved a mail with these photos and absolutely no text at all. just the attachments. it came from a gentleman from Brazil, that i got to know from the email firstname.lastname@example.org. All the images came under the name of Navio Motors. A frantic search on the google for Navio motors ended up in a possible link which was directed at Flickr, but the link had no motorcycle images. Pituco.com also was kind of a dead end.
Okay, I got another mail from the guy who actually wants to buy this ongoing restored bike but he is not sure if it is the NORTON 650SS. The frame definitely is from the 650SS. The engine... to what I feel can also belong to a Commander as the Commander crank-piston-air vents are slightly inclined than the more straight 650SS. But then I could be wrong. Anyone with any more insight? Email email@example.com or firstname.lastname@example.org
