I wasn't planning on listing it here, but if you are interested after reading this, I will set up a buy it now auction for you.....
It really is an excellent copy (when I first found it, I did not believe that it was the original 1989 edition) - 1989 W H Allen first/first. I think that a fair price (including P&P - first class post) would be £9.99 - but how do you feel about that?
