Plate and Saucer gobbledy gook for clever people to work out ~_~

My guess is that the 'sinker' is where the cup goes ....?

I'll have to print this out to make sense, Ev, but the first thing I have seen is shape numbers that definitely aren't saucers. Once those shapes are noted as such it might make the job easier. Evening work I think.

The A B C etc, are on the shape guide - that's all I spotted - yes I agree its a "print it off" and do some sleuthing

I'm hoping that it will help in some way to identify these pieces .......
There are drawings that refer to A, B, C cups/mugs, but they don't correspond to the shapes in the Four Digit Gallery.  I will add them now for reference.  
This is my favourite drawing, even though we have all of the shapes !!
