Found this link posted on the The Virtual Engineer forum. Kinda cool to look at, but they aren't organized in any order so if you are looking for a particular station, good luck. It's easy if you know the station's facility ID #, because they used that number as the file name. Some of them date back to at least the 1930s, maybe older. Newest ones are about the late 70's/early 80s.
