Question about bearing cones.

My missus has an Italian bike (Imperia) dating from, I'd guess, the
80's. The cones in the front wheel bearings are very pitted and creaky,
and I'd like to get some replacements. I got some 3/8" cones, and they
fit the thread on the axle, but seem to be too big for the 3/16"
bearings (after a while, they push the bearings out of the cups and into
the dust cap). 3/16" inch cones just won't fit on the axle. I'm
guessing that 3/8" cones are required, but that either I bought
badly-made ones, or there is actually more to it than just getting the
right thread size. I can't find much on the web regarding this, so does
anyone here have any advice about this. Of course, I should probably
just get a new wheel, but I like to keep original parts going for as
long as possible.

In particular they used to have a very extensive FAQ mostly compiled by

the late Jobst Brandt; I would start with that, and with Sheldon Brown's
