just-dig, those three things below the tag have been bugging me since you posted them. The iron piece you can figure to be a worn through double link for just about anything, but the two matching pieces are the challenge. It appears from the scan that one of those little arrow "devil's tails" has been broken off of both pieces, but on opposite sides. Is this correct when you look at them closely? Is there any evidence on the back that they might have had hinges of some kind on the bottom, such as what you sometimes find as closures on victorian photo albums? So far no idea what they are. Oh , one more question; as you fouind reeded instrument parts on the site, is their any evidence on those two objects that they ever had reeds attached by a small rivet on the backside?
