Comments De Laval produced cream separators and marketed them to farmers through their distribution network. With offices in several cities, only the NY office was known with control perforations. There is an early piece, dated 11/19/1909, but I don't have enough information to confirm it was used by De Laval. The postmark suggests not. Most likely a demonstration machine later purchased by De Laval.
