Help me identify these exhaust pipes

Any idea what Norton these exhaust pipes fit? I attached them to a head
to give some idea of how they fit on a bike. I am guessing a pre-Commando
based on the exhaust nuts. I suspect one of the off road hybrids
because of the loop for a spring to help keep the pipe in place. They
may even be an aftermarket pipe. I have never seen a factory Norton
pipe with the multiple angles instead of a smooth curve.

They look like they have been made to fit, so maybe a one off made pipes for a Norton, in 1980 when converting my Commando motor into the Featherbed frame I got a exhaust shop that had a mandle bender make my header pipes so that my pipes where tucked right in and as high as they could, took the bender 30 minute to make 2 pipes he did every bend by eye and after 37 years they are still on my bike but showing their age.

They look like custom "one offs" to me.
