I don't think its a question of hammer hardness. I thinks it's more the striking surface that is changed when we file hammers. If you look at the strings on these old upright, you will notice the strings usually are cleaner where the hammer strikes. Having a larger surface hitting the strings will "unfocus" the sound producing a certain harshness but the caracter of the sound will be a lot different. Usually you will have a lot of attack but the decay will be very fast and the difference of harmonic content between the attack and decay will differ a lot too. My two bits.
