[pianotech] stuck damper upstop rail

[Jude Reveley (Absolute Piano)]

All the "vintage" Masons I've seen have those 1/2" brass brads. Once I made 
the mistake of not reinstalling the brads and found the rail kept slipping 
no matter how hard I tightened the screws down. Not sure off hand why this 
is endemic to Masons and not Steinways. Angle of the bellyrail, lack of the 
felt strip backings, perhaps? At any rate, make sure that once you regulate 
the stoprail, either nail it back in or throw some washers behind the screws 
if you have the clearance.
