S. Newhouse O.C. #4 Trap with the flat link wolf trap chain & swivel. Trap doesn\'t look like it\'s ever been apart, at least not in a very long time judging from the nuts on the base. Has both springs stamped but nothing to brag about. The chain is what makes this one unique. Pictures are the best part of the description and please ask any questions. Meets all of s requirements for listing.
