I have a C6 Kingfisher LE I am thinking of selling but no idea of its worth, an ideas?
It is like new. Worn twice. Kept in its box(es) which even have the blue protective films in them which I removed when it arrived.
Have a jump hour, a C11 and trident in my collection too.
Just ordered a Bel Canto.

The Archive is your best bet.

It looks like very few to none have changed hands in the last 10 years or so.
