Thanks for the help guys
Yeah, the part I'm looking for is one of the bumpers for the engine that comes with the new Victorian Christmas set. Basically the base is still there glued in, but the round front silver part is missing...wasn't even in the box.
Anyway, via the info provided, I eventually got to their parts section an while this part is not listed yet for that kit, basically the train is just a revamp of the Hogwarts engine, an it is listed there.
Is only .80 for the part but I think I will go the route you have recommended as should be the way.
Only part that might be hard is the base seems pretty glued in, so might be fun getting it out.
Yeah, could send the whole kit back, but I've bought enough train stuff to know that it isn't rare at all that something is wrong with what ever you seem to buy in this hobby, an so could just as easily have something wrong with another kit, an then is closer to Xmas.
So far everything else with the kits it pretty much OK, (a few crooked things, but see above) but all in all I think I will just get the part.
Thanks again for all the help guys.
