Leica Black Nylon Stap w/ Pad & QR Connectors for R / M3, M4, M6, etc.
This is a nice black nylon strap with QR connectors that should fit any Leica or other camera with strap lugs. This one has a rubber pad for your neck/shoulder to prevent the strap from rubbing. I could not find any branding but it is similar to the counterparts made by Leica.
It is in excellent condition with light wear and works perfectly. The QR connectors show some wear but are sturdy and have plenty of life left.
