Hi
I can not recall having seen a free download,but when i have ti buy manuals i use these guys, they do a online download to save you shipping.and also a sensible price.
I must admitt i have always given me excellent service.
they are in Oz so there is a time delay of about up to 24 hrs.
They have a whitley pilots notes. A.W.38 Whitley
I'm a newbie on this forum with an interest in Whitleys. Thank you Brewerjerry for posting the manual and Slim Sam for releasing it. Much appreciated. I will forward it to my father, a WW2 Whitley pilot who now resides in Western Australia.
