Reeving a fiddle block with becket and single block?

Hi, I'm restoring the rigging on my new to me boat. The halyards were in bad shape and just really rags hanging on the mast. I couldn't make heads or tails of them, most were missing. The blocks however were intact. Gaff rigged schooner. All of the halyards for main and fore have a double fiddle block (i.e. two sheaves stacked on top of each other, upper one larger than smaller) with becket shackled to mast and single blocks on the gaffs. If I splice the end of the halyard to the becket on the fiddle, then run it down to the single block on the gaff and back to the fiddle, I have an extra sheave on the fiddle. I'd appreciate any help/ideas. Not huge sails (34' Colvin Saugeen Witch) but any extra power hoisting will be appreciated!

I'm really struggling to visualize what you have - pictures would help. Here is a quick sketch of the "standard" set up on the small gaffers that I grew up with - maybe that will help. Also I think Tom Colvin is still about, maybe he can provide a diagram.

Thanks for the sketch Geoff. For the throat halyards, that's what I get when I splice to the becket on the bottom of the double fiddle and reeve to the single block on the gaff saddle. But I still have an unused sheave on the double block. Hate to waste it, but it seems like I need another double block on the gaff saddle instead of the single that was on there.

In the pic, the upper left fiddle block is shackled to mast, lower right single is shackled to gaff saddle.

So is it just the throat halyard that has the double block? If so it could be to help even up the mechanical advantage with the peak halyard.

Maybe something like this or even with the halyard run the other way over the lower sheave and then attached to the gaff. I am guess guessing how it might be intended, I don't actually know.
