I remember. They turned out to be Melonette Jaspee de Vende and came from Flowerlady I think. Official description is:
Golden yellow, round and netted,(which means like the surface of a canteloupe)
They grow to 3-4 pounds,the flesh is orange.
They are by the way the same family as most courgettes so they would easily cross with one.
Me thinks they did.
