One of the main retailers here in Ireland, told me when the baby GMs went on sale years ago, he had a number of clients who bought one of every single running number available from him, and one client bought four of every running number. Who in the world would want that many locos unless they have a tennis court sized layout, or are trader/collectors hoping to make a few bob profit in the future when the models are out of production? I don't get it.
I am lucky to have eight baby GMs, four 071s, a single 201, and hoping to buy three or four 121s next year when they are on sale, but I won't be buying one of every livery or every running number. Hopefully over time 2xB&T 1xIR and possibly 1xGrey, which will nicely complement the existing GM fleet on the layout.
