Not sure if this is the right place to ask. I have to replace the fire basket in my old Edwardian/Victoria fire surround. The present basket, (old - broken) one is flat, with three legs, bowed at the front. Measurements are roughly 13.5" across the front, 10" across the back, 8" deep. I have tried internet, locally and cannot find anything to match. If I had one made it would probably be expensive but can anyone suggest suppliers? Photo attached of surround. Many thanks for any help.
