I came across this site today which seems to indicate spares for Arnold in it's present incarnation as well as it's previous.
It might be the type of site to bookmark:
Christian Krella, at www.arnold-ersatzteile.de, is excellent! I now have three new motors, one for a 93 2-8-2T, the same as a spare for an Ibetren KofIII remotoring project, another for an 18 4-6-2 and three new dome covers (two for the spares box) for the 93 for 106 Euros. Prices for a motor seem to be around 30 Euros on average.
