Pianotech

I have two clients with Steinway D concert grand pianos in their homes and  I'd like to educate myself to become more of an expert on these instruments.

What is the difference between a Hamburg Steinway and a NY Steinway and is there a quick way to instantly distinguish the two?

Is the Wippen the major difference or are there other differences?

Where can I learn more and educate myself on Steinway piano?

 I'm currently trying to improve my knowledge of the Steinway piano.  What resources, books etc. could you recommend to me?

I'm a reader, so book recommendations would be taken most seriously!  Does Steinway provide training to independent piano technicians?

Thanks!
