dbf, having ploughed through this monumental thread (not easy to keep up!) I've just got to say; 'nice one'.
I reckon you do the Irish Guards history a great service, rarely has so much solid stuff been concentrated in one place here. Hopefully the people who potter on while looking for some lost relative or other will really appreciate what you've done, and the obvious amount of work involved.
And as for 'covert pigeon lofts'... that's really led me down some strange Google alleyways.
Cheers,
Adam.
