Now I wish I'd uploaded the pictures from that eBay auction. It was a very similar bike with a "Celeste" decal on the top tube.
This bike on flickr is identified as a Dawes Celeste:

Note the very similar features - those chromed head-tube rings, top-tube pump pegs, cable stops at 5-o'clock, stamped dropouts with an integrated mudguard eye, four metallic bands on the seat tube...
Calmes dans le demi-jour
Que les branches hautes font,
Pénétrons bien notre amour
De ce silence profond.
