A Bulldog 200Q caravan / trailer stabiliser with mounting to towbar, bracket to trailer, tension release handle, blade lift handle, locking screw, spare 2" towball and selection of mointing bolts (these may or may not be the correct size).  Worked perfectly when last used - about five years ago, not tested recently as we no longer have a caravan.  Due to the size and weight this would be best collected in person.
