I have studied pistol lanyards for decades. The lanyard you show pops up fairly frequently. As best I can tell it is for a large loop revolver like the Reich revolver or similar. It has no separate swivel or attachment like the Luger lanyard. The diameter of the round leather is way too large to go into anything but a fairly large lanyard ring as it has to be looped inside itself to attach. Value? Sad to say it is likely minimal. I have a foot square box of these on a back shelf. I have never figured out a way to market them to make enough to warrant the effort and bother of selling them!
Ken sent me this photo earlier today and also a link to Simpson's. Someone there mistakenly believes it to be a Luger lanyard. They want $350 for theirs. Since there is no way to attach it to a Luger, I believe they are misinformed.
