Auster fabric covering question

Hi,

I am helping to recover an Auster and wonder if anyone has a copy of the repair manual that they could look at and tell me what is the spacing of the rib stitching on the elevators please.

I have borrowed a copy to get copied but sods law that page is missing. Its fig 10 and on the back has paragraphs 38-41… if any one can copy these 2 pages for me as well that ould be great

Many thanks

Ken
