longer ron: Yes, I think that shows the arrangement as I remember it. I was in the right hand/starboard side seat, which slid fore and aft on runners until locked in position. Looks a bit "fixed" in this drawing at the top, but it definitely did move!
Certainly, the two seats as depicted here alongside each other in a dual-control configuration are not of the ejection type. If that is the bottom of the navigator's seat behind the port side pilot's seat, then as drawn it might have been a bang seat, and if so the section of fuselage above it would presumably have had to be exploded off before firing.
