I also found an on-line version here. http://books.google.com/books?id=OBF...page&q&f=false
There are several places in India that offer free shipping in India for Spackman's book.
Amazon.Com has reprints available. http://www.amazon.ca/Trout-New-Zeala.../dp/1444649760
There was also a hardcover version at http://www.buy.com/prod/trout-in-new...210783833.html
No connection to any of the vendors, just a Google happy guy.
