A brass Kit Bag Lock with built-in lock.
Most Kit Bag locks are used in conjunction with a padlock but this version has its own built-in lock. This lock could be used to secure the two handles of a bag, such as a Kit or Gladstone together or to fix it to some railings etc. whilst travelling. The shape of the lock also meant that it could be used as an additional handle to carry the bag. This one is a little later in date than most and more refined. The handle has a fixed bar which swings closed to meet the built-in lock.
This type of lock would have been useful to any traveller, whether they be a salesman, soldier and could, of course, have been used to secure a variety of items apart from a bag. Circa 1900.
