Help indentifying flush plate manufacturer

[jukplum]

Hi, I recently moved into a new house and the flush plate on the wall hung toilet is broken. unfortunately there is no manufacterer label printed on it, or the cistern (concealed). I've tried buying one of the same size, but the back mounting plate was different and it won't flush properly. I've attached a few photos of the flush plate and its mount.
It metal, chrome in colour and is 245x165
Does anyone know who makes this?

Thanks

Joe

Looks to me like a geberit

Could be a geberitt omega.

Ditto, geberit

Don`t think I`ve ever seen a Geberit without the name on the front panel somewhere. Usually top right hand corner,

Sure its not a siamp?

 

[SimonG]

No not Siamp.

Grohe?

No not Siamp.

Grohe?

Simon, it`s not best of three and you can`t phone a friend! lol

Would a photo of what`s behind the panel help the forum?

Damn. Out of lifelines.

Looks like one I did last year, some generic tat from bathstore or victoria plumb.

That reminds me. Need to order a Dudley pneumatic flush valve
