[CR]vicini bicycle

hi everyone, I have just bought this bicycle :

Campagnolo nuovo gran sport group. Do you have any idea what is the most likely year of production of that bike ? Is this columbus tubing ? It does not have any columbus marks.

My vicini does not have any columbus stickers, but there are BREV CAMPAGNOLO signs on frame, yet no stickers. Could you provide any information about vicini bicycles ? Is this top of the line model in production ? http://www.allegro.pl/item342483257_rower_szosowy_vicini_na_campagnolo_zobacz_.html (I doubt it - top of the line model should be equipped in super record group). The only information I found is this :
