Whilst tidying the attic I have found three mint copies of the second edition.
I see that a copy is for sale on ABE for £180 at
https://www.abebooks.co.uk/servlet/S...iency%20badges
That is a rip off.
I offer my three @ £75 each to the first hands that go up.
Payment by Paypal, UK postage 2nd class included in price.
