A quick search on Google shows that, according to JRK of LL

Old Concert Pitch A=428.5Hz 

Currently Concert Pitch has A at 440Hz

This means that notes are currently defined as being slightly sharper 
than they used to be. i.e. A bell at 428.5Hz was once said to be 
exactly in A, now it is said to be a little flat of A.

This will make a difference to the note attributed to a bell when it 
was close to 50 cents between one semitone and the next one. If my 
maths is correct (help Bill H!) a bell that was previously noted to 
be, say A - 49 cents will now be recorded as being something over A-
50 cents and therefore be said to be Ab.
