Thanks for the reply Uwe, good to see you agree with Kurt from DARIVS ARCHITECTVS it looks like just what I am after.
My post above telling Kurt that I had found it was was buying it was a bit premature. I received an email today from Abe Books telling me the seller now requires an extra $42USD for postage.
I am on a small fixed income but that alone doesn't deter me from buying the book which I would love but I wont willingly pay
250% of the price for the book for postage with no guarantee of receiving it in less than 2 months. So for the moment it seems I will have to do without.
Sorry finished my rant.
Again thanks to you both for the excellent advice
Allan
