Joe,
Last email I had for the author was/is :
the_allans-fcla@yahoo.com
Not sure if it has changed or not in the past 1.5 years or so.
He was also listed in the NAPCA directory listing, but I think he gave up his membership and I do not have the listings from previous years.
Good luck...
p.s. He seems to sell his book on eBay from time to time...so you can try an eBay search by the book title...???
