that has to be one of the best lookin notrton rigid frames ive ever seen.
my first bike was an 800 dollar norton, that some wishful thinker had welded a rear section onto a stock commando frame. terrible job ,and it looked just as bad as it was. found a rigid triumph for 400 bucks, "gave" the norton to a guy who did nortons for 400 bucks, and started a lifelong love of britbikes
finish it, please, and post the build.
love that rear fender
