Ok it's after 8PM and no one is really really close.

Answer: The damper upstop rail was warped inward at that point to where it 
was almost but not quite touching the belly bar. The upstop rail had washers 
between the rail and the belly bar thus holding the rail away from the belly 
bar. When the three keys in question were played ff the middle key would move 
the  underlever hard enough to make the rail 'slap' the belly bar, thus 
producing a "click" type noise. When the keys were played fff  all three keys 
would produce the same type of 'click' noise. No other keys displayed this 
attribute.

 Since the upstop rail was a one piece affair the removal of said rail was 
not an option at that time. There also was not enough room to 'shave the back 
of the rail in position...so I took a felt mute, loosened the closest holdown 
screw. Put a little dab of glue on the mute tip and slid it behind the rail, 
trimmed off the unglued portion of the mute, tightened the hold down screw 
and no more 
clicks!! :-)

 I have never run acros this problem before that I can recall so I thought it 
would make a good puzzler.
Y'all were on the right track though! :-)
