Nova Chuck

[Bill21]

I recently bought a Nova PRO-TEK Supernova2 companion Chuck. I was somewhat surprised that the Chuck Jaws (Not the Top Accessory Jaws) were not numbered like many others on the market. I queried this with the manufacturers as replacing the Jaws in the correct order after maintenance etc could be somewhat problematic without them. They replied that the numbers are underneath! I then checked a few pictures of the chuck online and some pictures clearly show numbered Jaws whilst others don’t. I don’t particularly want to take the chuck apart at this stage so I’ll have to take their word for it that the numbers are underneath somewhere.
I may report back sometime in the future to confirm/deny this in case it’s of help to others.
Attached are a couple of conflicting pictures Fron the net.

Update: I’ve found another picture online from a German website and if you look closely the Jaws appear to be numbered with dots. The bottom left having four and the bottom right having one. 
Number “one” Jaw seems to have the stop screw that prevents the Jaws coming out in normal use.
