Thanks IthaDan. I will wait and see if I can get some gum coloured 204 hoods from Velo-Orange (or if my LBS can order them?) - they currently show as out of stock.

Do you know how they got the name "Arabesque"? Is there a key identifying feature? Given that mine are 6207, does the 1984 - 1987 range seem right? That might help to pin down the date of my bike.
