( Updated) Some time ago Larry posted the Stanley Gibbons numbers for the new self adhesive Security Slit stamps on the Machin Forum. I have reproduced this post here just in case it is of interest to anyone.
"The Gibbons numbers are in! The Catalogue Supplement in the June issue lists the following numbers:"
Specialist Catalogues will no doubt break these down even further to incorporate the background security wording and oval cut variations.

Concorde Booklets (Updated)
I now have assured conformation from a reliable source that informs me the third Design Classics themed retail booklet to be issued in August will contain 4 x 1st NVI gold and 2 x 1st NVI Concorde special issue stamps.
Sorry for any confusion, I was informed (as above) that these would contain 2 x Concorde special issues, however I think this was a typo, the image below clearly shows 1 x 1st class x Spitfire and 1 x 1st class Concorde stamps. I am assuming that this will be the norm.
Hidden Code Letters
Again for this booklet, the Machin 1st NVI stamps will exhibit a hidden Code Letter in the wavy line iridescent 'Royal Mail' text. The 'A' of the word 'MAIL' is replaced by 'C' in just one instance - above the central cross.
Thus the word will appear as 'MCIL'
Using Douglas Myalls information, the hidden code in the background text C = ROYAL MCIL, C stands for Custom.
The booklets will be produced by Walsall and printed in Gravure on self adhesive paper.
