Thanks to everyone who responded to my request for information to
Prague, Czech Republic, I look forward with delight thanks to your
suggestions.  I have decided to visit Budapest Hungary for 3 days
in the middle of my 12-day visit and would appreciate any input for
visiting there especially places to look for "mechanical musical
treasures".  Best Regards,
