<HTML><HTML>Fred and others-- With my harpsichotd experience limited to a large (4 registers) but cheap Sperrhake and a couple of smaller instruments, I can only reply to your question 1. Many years ago we had all of the jacks of this Sperrhake fittef with new plectra by the German manufacurer. This was an extreme hassle (packing & shipping) as well as rather disappointing, since I had to return about a quarter of the jacks since the work was so poorly done that they were unusable. We hired a "professional" to do the final voicing after I had reinstalled all four registers and did a preliminary regulation. This guy, about whom both my friend the owner and myself wrere suspicious (very  disorganized toolbox), did have an assortment of plastic plectra. I recall -- after 20 years -- that there were perhaps four or five colors, including pale green. What these colors meant I cannot tell you. Maybe thickness? Stiffness?  Sorry.
