This has repro fake stamped all over it - as bad as the gen-u-ine Cinelli badge was - I suspect a rip off from the US this time. It looks like a modern cast something or other made by the same manufacturers that sell the cheap belt buckles, and certainly not the usual lightweight etched or stamped brass or alloy items that adorn most British lightweights once transfers fell out of fashion.
I may be wrong, and I'm sure some Hetchins expert will jump up in indignation, but something smells exceedingly fishy about a half pound head badge....
