I know Henry, but another Luger said the coatings are of a different color
depending upon the glass used...such should be reasonably obvious.  Guess I
will have to go to a store that has several of each lens, and compare
colors!  Heck...I can see the scenario unfolding...we will start to collect
different colors of summilux lenses...wonder which color will be the
rarest....should start to see the depictions turn up on Ebay.  "Blue green
coating on this summilux...almost as rare as the green blue with a tinge of
turquoise..."
