Thank you to all of you for your support and feedback, and for asking help with your friends and colleagues.
- I very much look forward for the official BA seat map. It will be a wonderful reference.
- Seat pitch edited to be 38 inches
oopsie 
- It would be really helpful if I can get the exact pitch of the window spacing. I have looked at numerous photographs, and counted many many windows, but it seems that members of the BA fleet have different number of windows, sometimes the same plane would have different number of windows on the opposite site of the fuselage. The window pitch information would allow me to exactly scale my drawing correctly. For now, I will leave the windows unchanged as a baseline reference for additional feedback.
- What are the spaces between second set of doors and row 11 for?
bathroom on the left hand side in front of 11A/B
- Is there a CSD office?
Don't think so
- How about the spaces behind row 26 and in front of door 3? Are they closets?
- Does anyone have a apicture of the gap in the cockpit console that is created in flight due to the frictional heat? I believe one of the cockpit crew left his cap/glove in the gap deliberately for the Concorde's last flight to Seattle, but the cap/glove was ignorantly cut by someone else? I thought this is particularly sad, and actually is one of the reasons I am doing this seatmap to preserve some small part of Concorde.
- I assume the Mark meters are on the row 1 and (row 11?) bulkhead. Is this correct, and also are they only on the right side?
Yes they were on both sides. Although the left hand side was reserved for altitude in feet and Mach speed. The right hand side rotated between 'Distance to Go', outside temperature, Speed in MPH and something else that passes me by at this time
- As I am typing, I keep resisting the urge to say "the Concorde", and just use "Concorde" instead. Please let me know if this is correct, as I want to pay the respect that Concorde deserves.
There were more than one Concorde aircraft so it is 'Concorde'. If you are American then you probably have the urge to say 'the Concorde'
