piano actions

[pianotune05]

Hi everyone,
My neighbor  has an old upright that his daughter uses for practice but 
needs quite a bit of work. He mentioned that some hammers were missing in 
the trebble section.  I have a couple of old actions here in my garage from 
old uprights that are not is as bad of shape.  Is it possible to take one 
action out and replace it with another if they both were from old uprights? 
If this question is in the archives, I apologize, but I'm honestly not 
certain how to use the archives. :)  Thanks everyone.
Marshall

Yes, the plate was redone.  And your suggestions might be a clue.

Did you repaint the plate? Perhaps the new finish was less gummy than the
old.
