Not trying to bash the Paramount, but do realise that the pre '62 (or is it '63?) models were a bit heavier:

Cranks: Stronglight steel double
Brakes: Weinmann 999 standard, Campagnolo sidepulls optional
Seatpost: Campy Gran Sport optional, alloy standard
Bars/Stem: M.K. International Alloy bars/Eiam steel stem

The Stronglight doubles no doubt added at least a pound or two extra, and the stem probably half a pound. I am not familiar with the wheels used during this era.
