I meant gluing and truing of course, but to me, these examples cannot be as effective as some completely round ones.

However, I will g+t them on some hubs and will compare them against some perfectly round N22s.

The older nsr tyres cannot be simply skimmed. 
Only the full glue and true treatment gives them any hope of working. 
Any pair of tyres has to be trued to the same diameter on the wheel to be ready for the track.
NSR tyre prep is where knowledge,  money ( a Hudy ) and patience pays dividends. 

I borrow a truer when I have to work with NSR supers, but the truth is, they are a lot of work to get right.
Consequently, I use NSR reds for club racing and 5260s when the host event or club forbids non-black tyres.
