tuning Ricca 1913 to 440/435/25c flat?

[Stephen Airy]

I forgot to mention - the bottom board has a crack along 80% of the length 
under the pedal assembly, but the pedals still work -- the sustain pedal 
isn't quite sensitive enough though and the soft is a bit too sensitive.

 > I have the Ricca & Son piano I've mentioned previously in postings, and 
I plan to tune it (AGAIN!) tonight.  I just tuned it the week before X-mas 
but it already sounds bad!  The piano is right next to the back door, with 
the front door down the hall, and a wood stove across the 15-foot room.  I 
had tuned it around A-440, but the treble likes to go flat quickly.  I was 
wondering -- should  I leave/put it back at 440, or put it at 435 where 
pianos made in that era (1913, and this piano isn't in very good shape), or 
tune it 25c flat to compensate for when I play with recordings, some of 
which are 50c flat and others of which are at 440?  When I originally got 
the piano last September/October it was at A-415, or a semitone (100c) flat.
