Hi Wim,
    The shorter string (4 foot) should pluck first. The plucking of all
three strings (including the other long (8 foot) string, when both manuals
are coupled) should be staggered, one after the other, in an even way. What
matters is evenness of touch, so one note doesn=B9t feel more resistant than
the next. And you need to fit all three plucks into the keydip distance,
making sure you don=B9t have a bottoming out problem, especially in the bass
where strings are more flexible, so plucking takes up more keydip. IOW, the
distance between plucks is negotiable, but you should be able to depress th=
e
key slowly and hear/feel each pluck separately in turn.
    You=B9ll probably need to make a replacement lever. You could trace what
you have, and send it to Hubbard or Zuckermann and see if they have
something that will work. Or maybe try Instrument workshop (fortepiano.com)=
.
But they vary so much from maker to maker that you will no doubt need to do
some modifying, whatever you start out with.
    BTW, the name of your harpsichord maker is (was =AD he=B9s long out of
business) =B3Dowd.=B2 And it=B9s =B3plectrum.=B2 Not to be picky or anything <g>.
