Replacing Steinway hammers

[Horace Greeley]

Hi, Ric,

Where is the centerpin for the hammer shank relative to the drop screw?  Are
the positions reversed from normal?  Also, what is the profile of the jack
like, especially the 3 - 5mm below the top surface on the knuckle side of
the jack?

Thanks very much.

Best.

Horace
