I think prototipo is right though and here the combination of the wheel with engraved "Ferrero" signature (rather than stamped), the horn button (also unique to to Stratos?) and hub/boss almost certainly confirm the 'provenance' as original Stratos.
I'm sure you could spend less money recreating an exact replica(s) in new condition (as Gerry has done?) but for some that could never be original and therefore never as valuable.
Madness?!
