The internet is your friend
The most obvious difference between the two tanks (T-54/55) is the dome shaped ventilator on top of the T-54's turret. They are on all the different variants of the T-54 regardless of the shape of the turret. The rotating floor was first introduced in the T-54B variant.
I was hoping for literature, but thanks anyway.
