This piano have simply dropped to around 420Hz because it's not been tuned for too long, that means the strings are not tight enough to meet their designed pull pressure, that's why the bass strings are not vibrating long enough. As well, the bass strings are too old and the copper spiral have lossen up, this can be fixed by loosening the strings and rotating the strings clockwise and install it back on. Of course, tuning experience is required or you will pretty much break some strings for sure
