I think this may be some type of vintage fishing minnow trap, but I can’t be certain of this. It measures approximately 6 inches wide 5 1/2 inches deep and 3 inches high. It came with a job-lot of old fishing tackle - hence my assumption. If anyone knows if it is or thinks it something else please let me know. condition has shown in the photos which form a very important part of the description. Please study these very carefully and ask any questions before buying.
