My grandson gave me a beautiful Course & Speed Calculator manufactured
by W.C. Pye & Co Ltd. The mahagony box is marked as REF. No. 6B/120. It is a MK IIA model. It is obviously analagous to a very early E6B. My guess it is WWII era, maybe a bit earlier. Does anyone happen to have an instruction manual for this device? I can probably eventually figure it out but it would be a lot easier with the manual! Thanks in advance for any help. Jack |

If you type "course and speed calculator" into google, the first result is this:
http://www.adrax.com/watsons/raf.htm which has a picture of something that says MK IIA. DGB Jack McAdams wrote: My grandson gave me a beautiful Course & Speed Calculator manufactured by W.C.

Thanks, Dave - I saw that but am really looking for the book, not an
auction for the device. Jack Dave Butler wrote in message ...
