I just did a search on 1408 on my break here at work and looked at some images. Well, besides a few pictures of 1408, 1400 and 1435 popped up. There are good pictures of those two, but I think the smoke/steam that is in them is probably from a dynamo since it is back towards the cab and is more of a constant cloud than a spray like a whistle.
I'm sure that there are more pictures out there, just have to dig a bit more. Have a look at those and maybe order one of the books from Amazon unless you already have it.
