And here is some additional info. From http://hhscott.com/e_h_scott_2.htm:
E.H. Scott had several competitors. The most significant among them was a dashing young genius named McMurdo Silver. Silver was a continuous contributor to technical articles to Radio News magazine (the predecessor of Popular Electronics) throughout the 1930's. He was a polo player, gun collector, and is said to have been quite a bon vivant. Formerly the president of Silver-Marshall, Inc., he set up the McMurdo Silver Corp. and began building custom high-fidelity receivers in competition with Scott.
While good, his receivers were never quite the equal of Scott’s. One of Silver’s most famous owners was Dr. Lee DeForest, inventor of the vacuum tube. DeForest owned a Silver Masterpiece V and praised it in the final chapters of his autobiography. Throughout the 1930s, Scott’s and Silver’s advertisements would do battle trying to “one up” the other’s in technical achievement. Features were stolen and lawsuits initiated. Finally, Scott won the battle and bought out the failing Silver in 1940. Scott then introduced a new, bottom-of-the-line receiver and designated it as the Scott Masterpiece. I do not know if the gesture was meant as a tribute to his archenemy or to rub salt in the wounds. Silver eventually committed suicide in 1947.
