Rear brake reservoir lid & screws

[M65]

Im looking for a lid for a rear brake reservoir from a K3 650. Ideally I only need the screws from it but I dont know what size etc they are. If anyone could tell me that would be a big help. Failing that, Im happy to buy the lid and screws together if anyone has one for sale.

Cheers peeps

Anybody out there have one of these, perhaps from a bike being broken etc?
