Help on Wooden Mast Head

[filiperosa]

Hello.
I have the mast and some parts of the rigging left from the previous owner.
Anyone have idea how they fit? Please see the photos.
Regards,
Filipe

The oval shaped things are sheave cheeks, the round things are sheaves and the square things with the hole in them look to be the mast trim at the deck. The oval thing with the square end appears to be a masthead cap.
