A friend/neighbour gave me a page out an very old Model Engineer Magazine and on the torn page it says ME exhibition 30 DEC 1959 – 9 Jan 1960 does that ring a bell. Interesting to me in the text, it relates to a book, the title of which is “Practical Armature Winding” and the author was A. H. AVERY. Has any one got the book and would they like to sell it to me. I have already looked else where. John
