[Leica] IMG: Takumar in the Sunshine

[Jim Nichols]

Thanks for the offer, Curtis.  I explored those last week and could find 
only two choices, small flashlight or large, expensive light.  I 
mistakenly assumed that the large ones might develop too much heat.  I 
am nearly finished with the sunlight treatment, and, on examination last 
evening, the lens appeared fine.  I will give it a couple of more days 
and call it complete.
