Help to Identify Toilet to get Replacement Parts Drainage and wastage systems and plumbing help, advice and answers

[mth]

Hi all,

when the button to flush my toilet didn't work that well anymore, I decided to have a look into the cistern. The lid didn't come off instantly so I did the straight forward stupid thing and put a bit more energy in it - the lid came off but burst into three parts.
I now try to identify the toilet manufacturer and model to get the replacement parts. The only thing I could find were three numbers that are printed/ embossed on the inner side of the lid. Unfortunately, I don't know which number means what and searching the internet didn't give anything definite. Perhaps someone of you has a better idea. A picture is here:

The first digit of the long printed number seems to have been printed over (intentionally?). I think it was a '4', making it a 4518. The embossed one is 19 044000.

Any help is much appreciated!

chances are you will not be able to just buy the lid on its own, but you can buy the cistern with lid separate from the toilet pan,

however it does look like a Stax SupaPlumb toilet,

Hope it helps
