The Case! S2 came with a case but leather does not live for 73 years and those are not Nylon threads The case protected the S2 well in storage but came apart at the seams! literally.
Coincidentally I had a Nikon SP limited case laying around, just in case an SP limited with the 3.5cm 1.8 stopped by for a visit. I do have the S3 2000 case as well, a lighter color.
All these cases have a weak spot where the front cover flexes at the base, resulting in cracked leather, not sure how usable they really are.
