Well, to answer my own question,- Yes there is a VERY interesting place to visit:
http://www.generalsociety.org/exhibits/default.asp. According to others, it is one of the largest collections of safelocks in the world.
Unfortunately, I have walked passed it within meters, without knowing. I did not fint out about until I returned home, after my 1 week stay in New York.
However, I have ordered the book,“The Lure of the Lock†by Hopkins, and hope to order the CD of the collection.
Another place I had
planned to visit was the Greenwich Locksmith. Unfortunatly, I did not locate it until after closing time on my last day of visit. Will post some nice pictures of its decorated facade(spelling?), with thousands of keys made into different patterns.
