Comstock / NYC Norton reed breather banjo washer size?

Bonzo said:

I have a slight weep around my reed breather valve in the sump.

I have spare sump filter washers (part# 067680), but the valve comes with a couple of copper banjo washers.

Can anyone confirm what size washers I need before I dive in to investigate?
