Agree, all 3 are Akro lifesaver corks, the wonky one in the middle looks to be a double ingot. Corkscrews don't have to make a full rotation to be considered a corkscrew, whereas a patch will go straight from pole to pole. Corkscrews are identifiable by having two or more spirals going from pole to pole w/o intersecting. I don't see oxblood on the first one, just some darker trans. red IMO
