BMC ‘A’ Series
Tuning Manual
by J.H. Haynes
circa 1965, 122 pages, paper back

Donated by Seth Jones, this book is an older version of the Hayes manuals that we all know and love. Paperback in size, not the current larger format. It would be interesting to compare to a more modern edition to see how tuning techniques and theories may, or may not, have changed over the years.
