Have seen these around just a handful of times since I started collecting... finally snatched up a pair myself. But I don't know anything about these devices... anyone have any information on them? Timeframe they were worn? Any photos of them in use? I have several of the regular lyre devices that were described in the early regs but haven't seen any documentation on these kind...
