Mervyn,
It has been a while, hasn't it? My absence is due to a few factors; a cross country move, being a member of too many internet for a and getting a bit burned out, and I have not been actively collecting for a few years. But all is well with me, thanks!
Richard's book is of a similar scale as Brian Robson's book, but with a focus on cavalry swords. As far as I know there are two distributors of the book--Richard himself through his website, and Stuart Mowbray in the USA.
