Identify This Hinge

[DieselDennis]

Project from LOML.  This pair of hinges goes on a round folding table that the top folds into different "pie pieces".  

Obviously it's a concealed hinge, but that's about all I can deduce.  Woodworker's Hardware didn't have a match.  This isn't really a cabinet door hinge, but I suppose if you had a cabinet door that you needed to open a full 180 with a concealed hinge, it would do it.

One of the hinges has become very hard to function.  I believe it was bent and now is really stiff if it bends at all.  

No brand name, maker mark, number, or any identifying charateristic can be found on them anywhere.
