Appears to be a #4 Newhouse frame with what I've been told are probably Hawley Norton jaws and posts. When you try to set the trap the jaw lands on the pan pivot so they aren't correct for the frame. The springs are very strong but with light overall surface pitting so no stamps are visible. It has a cast clevis but no chain. The smooth pan is mostly readable and says S Newhouse Oneida Community. Can't really see the first half of Newhouse.
