Ultra Rare Collector's Item MBROO Metal Waterproof Case for Barnack Leica, Thick Thread I was collecting this for my Elmar 50mm f3.5 L39 Barnack Leica IIIf. I'm selling it off as my collection has grown. This is a very sturdy metal case with a great feel. It's a very rare item, with very few available. I believe it's from around 60 to 70 years ago. It's amazing that it has survived to the present day in this condition. Regardless of whether it's still practical, the craftsmanship and the crinkle paint are cool. This is what it means for an object to speak for itself. ▫️Appearance▫️ There are some scratches from aging, but no dents or major scratches, giving the impression that it's clean for its age. I have cleaned it thoroughly, so it's cleaner than when I bought it. 1. Opening and closing function works fine, but it's unknown if it's waterproof. ▫️Accessories▫️ None ▫️Notes▫️ The condition is based on my subjective assessment, and since it has been in someone's hands before, please check the images carefully and purchase only if you are satisfied. Regarding the color, the color may differ depending on your monitor and the lighting used for the photos. I will post many images so that you can see the colors as accurately as possible, so please understand and purchase accordingly.
