Chrome / crystal type ceiling light (Gloucester GL2)

Used ceiling light - pictures show a matching light we have in situ still, and the fixture we are offering removed a while ago and was working fully, and awaiting a new home. The chrome plate is 25cm diameter. There is a missing ceiling bracket needed - 180mm / 7inch, (can be seen) and be replaced from amazon. 2 LED bulbs and 1 halogen bulb in situ.
