Hi, I've come across a tap washer with NO hole in the rubber.

Hi,

So this is a first for me to find this but at least it's in my house! Most old sink tap washers have a hole but this washer doesn't and it has 86 (or 98) embossed where the hole would be. Diameter of its seat which looks like an olive is 17/32.. Any ideas? Am cutting the rubber away but maybe it's an obsolete article !!
Any ideas ? Thanks.

Do you mean something like these, only without the pin in the centre?
