I have a large Office World Black 4 drawer filing cabinet for sale which can be collected from South Birmingham.
Height: 52 inches (132cm)
Width: 18 inches (45.8cm)
Depth: 24.5 inches (62.2cm)
It comes with locking key and has a few bits of wear and tear and is in perfect working order.
It takes foolscap suspension files and I can throw some of these into the sale as well (FREE).
