This will replace your broken case and is a perfect fit and comes with the line in grommet
No picture as yet but it is perfect.
This is as good as the real thing and has been moulded to the same specification as the GPO. It is made from ABS plastic and so not so prone to chipping or cracking as the original Bakelite. As you can see it is stunning the tooling for this was a massive expense. You will have to supply your own bell-set internals to use this.
