I think the original may have been nyc.zip since I sometimes rename things to make them a little more recognizable. At any rate, I spent about an hour trying to find it also and no luck. I've had it for more than a couple of years so it's possibly no longer available. If I happen to sumble across it again, I'll let you know. Fantasticarts.com has over 45MB of architectural models you can download free but I don't see listings and you have to use a p2p client to get the downloads because of the file sizes.
