Personally, I HATE the extended smokebox and headlight on top, instead of hanging out on the brackets. The aesthetic proportions are just all wrong. Also, very uncharacteristic of the South Park. I also happen to think the Congdon stack was the zenith of good looking early stacks and as a result, I tend to dismiss the fancy capped stack as part and parcel of that extended smokebox abortion. But to be fair, the stack itself is pretty darned cool. The Puffing Billy line runs at least one of their locos with this style stack. I'd have to check my photos from that visit to recall what number it was.
