The fork of this 'dale was a "ritchey Force" not the top of the top with tange ritchey blades I think, but a good fork with tange. I don't know if it was prestige or not quality. The fork of my Merlin is a Ritchey Force which had this black-green kawazaki splats on it. But the steerer was short, and the pinting in a bad shape.
What length you need ? I think that any good Tange fork with long steerer or a Spinner would be fine. It's the first and more important choice. Respraying is not (neither) a problem.
So… ebay ?
The chance for finding that ? For my Merlin I really wanted a Bridgestone -ritchey lugged fork. Days after days, I looed on ebay… … nothing nothing nothing. When I decided to give up… This fork appears on my windows.
So , Sorry, I can't answer to this question.
But I keep an eye in France
Well… it's really not acceptable…
