Help with filling valve id please

[Atgni]

I have a constant filling loo dripping into bowl.
Could someone help identify the viva valve so I can order the correct replacement washer please.
The loo is not at my house so I can not take it to bits to see but have been sent these photos. Thank you

Viva skylo.

Thanks, but it doesn't.

Says vivasanitary.co.uk and then you visit that and look through their product list!

Even if you do have to scroll past PB Plumber's ugly mug to get there!

Ok thank you. Looks like a skylo bottom entry. Which uses the red nibbed washer
