Leica M6 TTL, Summicron 35mm ASPH. (Pentax Strap with 2 D type rings. same width and thickness all around)
I have taped it up to protect it for my journeys on bike or motorbike, it also gives better grip.
It also has small pitting on the body so the tape will also keep moisture out, and protect the paint some more, Im a sucker for keeping shit in nice condition.
I also didnt want a case as it would feel bulky.
