Well, I've just got my Bachmann 47 with sound, and I have to say from initial impressions it looks like a 47. The rivets are still on the window surrounds, but as it's a pristine finish they aren't clearly visible. I think with a bit of light weathering they'll probably be more noticeable, so there'll be a need to clean them off before doing that. The windscreen wipers are much finer than other pics I've seen, so they don't look in anyway obtrusive.
The only other comment I have right now (as my test layout is currently 'offline' due to house room re-arranging I can't run it to have an opinion on running and sound qualitites) is regarding the cab windows - while they seem to be about the right size, they seem to be missing the slight 'sad-eye' appearance of the prototype. It's not a serious error, and certainly wouldn't stop me buying more 47s from Bachmann when the right ones are released (Large Logo 47/4s, InterCity 47/8s and ScotRail 47/7s).
I suppose if I had a request for improvements, it would be to remove those window rivets, and slightly rotate the cab windows outwards to get the character just spot on
Score: 9/10 (based on appearance only)
