I think my earlier post may be too vague and confusing.
This might make more sense -

Gypsy: no crown cover, no chrome fork socks
Gypsy Sport: no crown cover, chrome fork socks
Gran Sport: crown cover, no chrome fork socks
Gran Sport Deluxe: crown cover, chrome fork socks

This is just a rough guide and I always keep in mind there can be anomalies.
