Short Stirling & RAF Bomber Command Forum

I'm trying to locate photos and drawings of Lancaster B MkIIs. I especially need drawings or photographs of the Hercules engines and also the bulged bomb bay doors which I believe were unique to the BII and not to be confused with the bulged doors used on BI BIII and BX types.
Any help would be appreciated.

Traweled the net and found these four which focus on the radials with a bit of bomb bay door bulge also visible in a couple.

Here is another link with many images, although seems to show all types ( searched on google images ) .......... https://www.google.com.au/search?rlz=1C ... CE4QvwUoAA

Thanks for the pictures but the front view of the engines showing the collector braces is illusive as are any photos of the bomb bay door interior. Some one somewhere will have a picture of grand father standing in front of his Lanc, we can only hope.
Thanks again.
