Atlas Production Racers

I recently borrowed some new old stock exhaust pipes that did not appear to fit anything to try on my 650 SS PR project . Not seen this design of pipe anywhere before . Similar to the very first Manxman pipes shaped to run closer to the frame but much more pronouced and run within a couple of mm of the front featherbed downtubes and have welded on brackets that appear to be for fairing mounts . Norton Exhaust rings that cant be removed. Been puzzling over these for many months. Then I am sent some pictures of one of the very few ( 2 or 3 ) ? Atlas PR bikes that the factory supplied to UK dealers . Bingo !. What are the chances of this happening?. Mind boggling.

Pics?

That's interesting as I didn't know they, & I presume you mean Plumstead, supplied Atlases for PR. Any idea what years they did this?
