Unfortunately, despite extensive research the brand for the filing cabinet that has a small square key with H29 engraved on it is still a mystery.
The best advice I could give would be to take the key, if you have it, to a specialist stationary or office store. They may be able to recognise the key and point you in the right direction to the brand of the cabinet.
Office filing cabinets are typically made of sheet metal or wood. The drawers usually have a drawer slide to facilitate opening, which includes an "outstop" to prevent the drawer from being pulled completely out of the cabinet. To open a drawer on most metal filing cabinets, a small sliding mechanism known as a "thumblatch" must be activated to release and open the drawer. Each drawer has a handle to grip and pull the drawer with. On the front face of each drawer there is usually a label holder to allow the user to identify the contents of the drawer.
Many filing cabinets incorporate a keyed lock to prevent unauthorized access to the documents being stored. There are two types of locks; a "cam lock" is activated with a key that rotates the lock and a "plunger lock" is opened with a key but can be closed by merely depressing the body of the lock. The plunger lock allows a user to quickly close and lock several cabinets in a short amount of time.
Some file cabinets have a metal plate or wire structure at the back of each drawer; which is known as a follower block. The follower block can be adjusted forward to reduce the length of the drawer so that the file folders contained within remain upright and at the front of the drawer for easier access.
