Norton 850 Mk III

I HAD 157 bikes 2 years ago but Im down to about 50 now
 
I have three Nortons in my garage and plan on selling a couple. Problem is which one to keep. The Commando 850 I have owned for 38 years and is well sorted and reliable. The Atlas is a beauty with lots of goodies on it but the Mercury 650 is rare and probably worth the most when restored. I think the Atlas will go first and then comes the big decision.
