If it only pushes me to stop faffing and put out on eBay it’ll have been a worthwhile endeavour!
I sold my Rado as a full package to my local CC. It was sent off to be authenticated as they are faked apparently. Anyway they bought it. It was not a fake by the way
I would expect they get offered a lot of fakes, and it's getting harder to spot the best ones - caveat emptor !
I'd rather buy from a dealer with a more professional reputation.
