That’s a very nice commemoration, Robin. Let’s hope we get an equally bright nova before long. And thanks to Bill Barton for highligting the centenary.
Felix de Roy, one time VSS director, produced a series of articles in Ciel et Terre, Volume 36 of the Bulletin of the Société Belge d’Astronomie in 1920, covering the early course (and lightcurve) of the nova. In one of the papers he considers observations made before June 8. It’s in French, but makes an interesting read, especially the names of the great observers of the time.
