So does that mean the plate is present?  do you remove the action in order to access this or do like some might do and just tilt it outward toward you in order to access the screw.  Just in case anyone reading might wonder, I have had some exposure to this at the school. I just have trouble remembering which way the action was facing when we worked on this since it was already out of the piano.  I mentinoed this because someone e-mailed Don at the school and asked if I was trained because of some trouble I was having with another repair, but I cannot recall which one it was.    While I'm on this topic of remembering tasks, is this normal to neeed a refresher on tasks/repairs once in a whie?  I also have the Reblitz book.  I'm also curious as to how you guys know the part numbers off the top of you rhead like that amazing.  Oh just order screwdriver # .... amazing!  You guys are a great help.    So to ease any confusion, this is definitly not a flange screw situation.  It is a hammer but plate arangement. I've never seen this on an old upright before.  We had an old upright at the school with a weird hammer spring rail that used cord loops or some sort of arrangement. I didn t work on this one, but I recall it might have been from an old Bell brand piano.    Well thanks everyone!! I sure appreciate you guys Marshall Marshall Gisondi MARSHALL'S PIANO SERVICE 215-510-9400 <a href="http://www.phillytuner.com" target="_blank">http://www.phillytuner.com</a> </div></body> </html>
