Hi. Roger. the pictures of my TSB rigging blocks.

The top of the top mast. 2 single blocks, one for the topstay forsail, the downhaul is made off at the bottom of the main mast,the second is for the topsail head stick the downhaul is also made off at the bottom of the main mast. 
The top of the sprit one block for the topsail made off at a cleat at the bottom of the sprit, the second takes the vangs.

Three pairs of deadeyes each side, attached to the main mast shrouds.

The two topmast backstays have two single blocks one with a single strop or eye, and the other with a double strop, an eye at the top and the bottom.

The mainsail has two single blocks and double block to attach it to the ring on the horse.
I had difficulty getting my head around the rigging but when I started to rig the boat everything fell into place,and | am sure you will find the same.
Regards.
Eddie.
