Hi, I've just purchased second hand R2904 Black 5 "45190" from the Pete Waterman Collection that is now running well. However, there are a couple of small parts missing - the front vacuum brake pipe and the rear coupling eye from the tender buffer beam. Can I still buy those parts? The detailing kit was open but there are brake rods, steps, and sanders but nothing else. Should there be a crew? In addition, there weren't any cylinder drain cocks can anyone recommend some that I could add to this model? I'm a newbie here really so if I should post somewhere else please shout. Many thanks, Andy
