This was a near-score, but it's too good not to share. Picked up an M3 off Craigslist for a good deal, came with a non-matching Leica ever-ready case. The late owner apparently had boxes of Leica gear that the family had sold off years before (sounds like they didn't know much about what it was), but I was happy to get the last of their collection. That is, until I realized the leather case was actually an original case for the first MP with Leicavit...
Whoever bought that collection got very, very lucky.
