Many of you know that I've been gathering info on Commandos for quite a while and publishing it on my web site, see: https://www.gregmarsh.com/MC/Norton/CommandoSurvey.aspx
I'm trying to figure out several things. In theory, all 850s had a frame number stamped into the timing side of the headstock (not talking about the Red Certification Label). I have enough info now to be somewhat sure the early 850s did not have that number. The first one I have with the frame number is 306124 and the last I have verified to not that the number is 306028. I'm interested in all Commandos but right now I really want more between those two bikes.
Also, starting in May 75, the MK3s had a frame number that matched the rest of the bike. The first I have that matches is 332473 and the last that doesn't is 332351. Any between those two would help as well.
There could be bikes outside the ranges that dispute either of my assumptions. One reason is that it appears that when a bike failed test it could be long time before being fixed and dispatched.
I do not include any info that ties the bike to the owner and I don't even keep a record of the owner.
