"The Jacobs Bros. Co., Inc." in Brooklyn, New York was mainly known (in 1937) for Scale, Refrigeration, and Store Fixtures Assembling and Manufacturing Industry-Interference. Jacobs Brothers were also at least selling radios with their name plate fixed to the chassis. Changed name to Detecto and were then purchased by Cardinal Scale Manufacturing Co.1877

Appeal from a Justice of the Peace, No. 295, September Term, 1931: "Jacob Bros. Co., the plaintiff, claims that it sold and delivered a radio to the defendant on December 24, 1930, for the agreed price of $175.00 and that a balance of $100.00 is still due on that transaction." But the defendant claims that offered was a General Motors radio in a Jacobs Bros. Co. cabinet, but received was a model "Dafan" from GE.
