I would like to know if anyone can tell me what the attached item is. It was in a box lot I purchased at an auction. At first I thought it might be some type of thread or yarn holder. It is about 7 inches long, and on one end (the end with the lips), the side 'pulls up' maybe about a half inch, as if to load something in it. One side also has what appear to be brackets so mount this somewhere. Any ideas? Appreciate the help. Thank you
