I have owned my 1978-vintage Original 66 since about 1980/81. I am very fond of it. But I never got in to 10m match rifle.

Anyway, about 30 years ago, it stopped being a match rifle and became a scoped "precision plinker", at which it excelled - Swan Vesta heads at 6m being a favourite back in the day.

Which means, any number of house moves later, that I cannot find:

- the washer that goes on the front of the barrel sleeve behind the locking nut;

- the big wheel in the rear sight and its associated octagonal nut that holds the rear sight to the sight rail.

Neither Chambers nor any other site I've found lists these.

Any ideas? Beyond look really hard in every box in the attic?
