What are the changes to the shape at the top of mast as compared to the model 1.

Are the model 1 mast tops the same as the model 2 etc...? How many mast designs were made, and what years,? I am interested in the actual mast form (ie model 1 is a tear drop shape when looking from above). I know the recent masts have the sheave pulley wrapped in a black plastic at the top, where model 1 is tucked inside near top of mast. Thank you.
