This is most likely the old Howard knuckle type.  To the best of my
knowledge the regulation adjustment is relatively the same as a round
knuckle.  Line up the back side of the jack with the wood core edge in the
pear-shaped knuckle.

I have done this, however, I am unable to support this relationship with
actual resource material.
