Hi Andy,
I hope to get them from the printers in early Jan 2013.
I believe that it is a good publication with lots of new info in, especially, Appendix 4 which gives all the 'good stuff' about each officially (note the word officially) authorised badge by the War Office and MoD.
Contents are here:

I hope it covers quite a wide investigation into these badges.
Regards
Chris
