Hi Bob
Apologies this took a bit longer
I have annotated a copy of my Sunderland III to give you a general idea The Mk III and Mk V were quite similar
in the internals with the exception of the Beam gun postions)
As you can see its quite busy all over
First off there need to be a bulkhead where the steps are from bow to flight deck
The right side leads to the lower deck
Door on right is entry to toilet
Entry to lower deck Looking from Ward room)
Note the bunks for sleeping and folding table in centre
Galley
Sink/Bench/Stove - Note also the drouge storeage (x2 one on either side of Galley)
Other side of Galley, note Ladder from galley to flight Engineers position
Bomb bay
Bomb trolly
Bomb Bay door travel rails
Rear decking (note this is a Mk V so ignore beam gun positions) note work bench etc
Upper Rear deck (above crew rooms)
Oven/Church Door (leads to flight deck)
Flight Engineers station and Equipment rack
Flight Engineers station
Navigators Station In front of Flt Egn station
ASV station (behind Second pilot (Starboard side)
Wireless station (behind first pilot Portside)
Bow section Note mooring bollard if doing a water mooring scene
