I have both books. The Moore and Estes book written in 1957 and the Moore book that is based on the original but is much more extensive. I do not know if either book is still in publication. My Moore book was written by Robert Estes--3rd edition 1998. Mr. Estes lived in Mt. Airy, MD 21771 at the time of publication. Contact me at firstname.lastname@example.org
if you are reasonably close to where I live I could loan you my copy. Or ask me questions and I will do a look up.
