Only thing I'm not sure about is the real springs on the bogies, cosmetic only but they look a bit naff to be honest. I have a couple of the 22s and they're not a bad model, would be nicer with some tweaks and still not sure about the mechanism, she overheated on Brendan's layout, although that might have been the hornby sapphire decoder that was in it, which I'm not a fan of.
Still, the wizzo looks fab, and they're doing a 73 too, can't wait for that either.
