I really, really hope D1000 doesn't come fitted with any air pipes - I don't think it was air-braked at any stage in its life, and certainly wouldn't have been in 1962 Desert Sand livery. The only pipes at both ends should be the steam heat hose and the vacuum hose. See http://www.warwickshirerailways.com/gwr/birmingham-snowhill/brlocomotives/gwrbsh1321.jpg
I'm particularly glad though that it'll come pre-fitted with the lifting rings. It'll save my eyesight.
As for fitting the rings, I'd imagine that the sanest way to remove them from the etch is to first thread the fine wire through the holes down one side of the etch, place that side of the etch on a small length of blu-tak, and bring it to the attention of the Dremel drill (cutting disc attachment). Lift off the etch, and you should be left with the separated rings sitting on the blu-tak. Lift the wire, and they should peel away.
That's the theory. When my wallet recovers, I'll get a BFYE Western. Maroon, Golden Ochre, and green have never appealed to me, but I've always considered any Western in Desert Sand to be absolutely knockout.
