Question for Norton Factory UK

Hi TonyA
Well, the oil dipstick of a friend of mine he got this year from our Swiss dealer was even longer than the one I have since 2012. The high mark of that dipstick was about in the middle of mine low and high level marks...
Unfortunately, I still didn't get photos of this.
It might give some confusion about the measures taken. I guess your measures were all from the bottom of the threaded cap. If the thread has always the same length this should not matter.

Here are the pictures...

But this one seems to be made by the local dealer and not by Norton.
