[Leica] 49 to 46 Step down ring was Leica Service in Hong Kong

[cummer at netvigator.com (Howard Cummer)]

Dear Frank,
Thanks much - I will take the examples from B+H's page and shop them  
around HK. I'm sure someone will have one and then I'll see about the  
vignetting. If it's bad I will only be out a few bucks.
The LUG is such a great resource!!
Cheers
Howard
