Question about White Industries hubs
 

Approx 10 years ago I won a set of White Industries MTB hubs in a race.
Stayed in drawer until now: building wheels. I note that there is a small
(2-3mm) hole in each hub, which aligns with an inner hole when rotated to a
certain position. My guess is this has something to do with lubrication
access, but don't have a clue as to what to do about it: what the purpose
is, etc. Please help.
