During that period the vast majority of Hamburg S&S had only two pedals. S&S NY can tell you where it was made by the serial number. There are numerous clues when you pull the action. Action screws are different, shanks are different, hammers are different, wippens are finely finished, keys are different. They essentially are not the same piano as NY because they did not use parts imported form NY but those made my Renner. Older S&S plates had New York and Hamburg cast in the plate. There are so many difference that you will be able to tell immediately what it is. Europeans do use vertically oriented veneers inside the rim and NY does mostly horizontally. Europeans rare paint inside rim veneer the same color as the outside. Luck. Newton
