sluggish aeolian spinet action

[Eliot Lee]

Hi LIst,

    I have to work on a Hallet & Davis Aeolian spinet.  The action is very
sluggish and it isn't because of the keys which would have been an easy fix.
Any recommendations and/or short cuts? Is protek recommended or something
else like silicon/naptha that baldwin recommends.
    Would the real solution be to reflange all the culprits, this isn't an
easy task being a spinet.
    What about using heat on the action centers, with a modified heat gun?

    Any and all suggestions would help thanks,

Eliot Lee
