Here's a Nice Vintage Leitz Leica Leather "Ever-Ready" Case specifically for the 3G and 1G cameras.  These are cameras that might have a brightline viewfinder attached, and it's a little bigger than the cases for the III and II series cameras, which were a little smaller from L-R.  (It's taller to accomodate the viewfinder, and wider because the 3G & 1G cameras were wider)

It's in Very Nice condition---  with a very small cosmetic issues---  some light blemishes/scuffs/wrinkles to the leather, but otherwise strong and firm with no breaks.  The purple velvet lining is in nice shape too--- will keep your camera protected.    It has a bulbous nose which probably won't fit a rigid Summicron, but the collapsible Summicron or Elmar or Summitar should fit fine.   What you see is what you'll get.  
 
Continental US Shipping is 10.50.  It will be packed well and safe, but economically.   International Shipping via the ebay program.

PLEASE READ THIS--- By Buying this you also Agree with this:  I am not Amazon or a professional Store seller---I'm just selling a surplus of Used items. I try to be honest but I'm not into having things go back and forth based on Opinion, or risk "part swapping" either.  So it's being sold As Is, No Warranty, No Buyer's Remorse, No Try-outs, No Returns--- it's a used item with possibly unknown flaws.   I try to be detailed and truthful, but I can't describe every every millimeter of it, so there may be a nick or blemish or a couple specs of dust that I failed to mention... but they would hardly diminish it... unless you expect everything to be 100% Perfect and Like New.  Repeat--- this is a Very Old, Vintage, Antique, Used item so it can't be as new--- so please don't expect it to be.  It's being sold for collectible purposes.   What you see is what you'll get and I package my items well, so it arrives in the same condition as shown.
