Hi,anybody recommend a good technical book especially for B40 1965 on Have Haynes but not all info in there .

The Rupert Ratio unit single manuals are full of very useful information;

Thanks for that I had forgotten the name  .Have ordered one .

With Haynes and Ratio, can I add that its worth having a parts catalogue to hand which will show you what should be there, even when it isn't! I've found that the Haynes manual is the least helpful.
