Owners of Genuine Kits - Need a measurement! :-)

Hi folks can someone with a genuine kit measure the distance from the face of the lens to the outside edge and likewise near the back to double check its the same distance? pic below of the 2 measurements I'm after Many thanks

I'll have a look later for you mate

Ah cheers that would be great - need to know what the measurement is and whether its consistant all the way round (which I fully expect it to me). Mine gets thinner so want o adjust it.
