Good question that I'm sure has been asked a hundred times so shouldn't be too hard to find an answer to. There was one site I found very useful.
http://www.hydra-glide.com Sorry to say I don't have an answer for you but I did own a '57FLH and was curious about it's history. I brought it over from the UK about 8 years ago and then sold it three years later.
It shouldn't be too hard to find what your looking for because there is a lot of knowledgable and helpful people here. Should I mention talented too? Maybe even good looking.

cheers!
