This is really a great book. You will find everything you want to know regarding the Thorens TD 124 - the most classic record deck in the world (my oppinion :) )
Bang & Olufsen also sold a product with this Thorens TD 124 in 1968 (only one year actually) The B&O product is Beogram 3000 of 1968, this product belongs to the Beolab 5000 family. Because only one year in production at B&O this product is very rare.
In the book´you will find 2 pages of Bang & Olufsen and of course Beolab 5000, Beogram 3000. Find it on page 112 and 113. Guess who was invited to write the article regarding B&O

PS. I don't know simular books regarding other B&O products - unfortinatly.
