The GCRS website is now blessed with a growing number of online drawings from the archives. The great majority of these are only available to Society members through a password. However, this is a very good reason to join the GCRS, as the subs are very modest by modern standards.
For example, I didn't know that the GCRS had a dining saloon 'for football parties'. But I do now, and what's more I've seen the drawing.
