Identifying a toilet flush system

[Jimbo-Winch]

The toilet flush button (pictured with the flush system) has broken but I can’t find a matching replacement or a replacement flush system that matches the one I have. It has a bayonet fitting (pictured) which makes it extremely easy to remove/replace, hence I’m loathed to have to remove the entire cistern to install another system if I could find a drop-in replacement for what I have.

There are absolutely no markings or writing on any of the components to help identify what make/model they are.

Toilet is in an extension built 4 years ago, so assume all the parts are from then.

Grateful if anyone can help identify.

Amazing, thanks for that help. Yes that definitely looks like the part.
