BT Decor phone (receiver) (BR4 - West Wickham south side)

It's a long shot, but ... We think our landline phone receiver is broken - we can't hear any callers unless we put speakerphone on - so in the interests of not junking an otherwise good phone I wondered if anyone else had a functioning spare BT Decor phone receiver that needs rehoming. If so, we'd appreciate a photo first so we can be sure the receiver will fit properly on the cradle. Many thanks.
