Actually, the Massey 8780 is basically the same machine as the White 9500 prototype combine, one size down from a 9720. Edgar S. Martin Equipment in Wallenstein, Ontario had one of the working prototypes in his yard for wrecking purposes, since the engine, tranny, and many drives also fit a White 8920. I beleive he bought the machine directly from White's receivers, on condition that the combine was to never be sold as a "whole good", since their never was a parts book published for the 9500. Massey was experimenting with their own prototype combine called the TX903, which was very common BUT NOT IDENTICAl to the 9700_9720 White. Patent infringements and "poor financials" prevented Massey from "tooling up" to produce this combine, that is, until White went broke and indirectly sold their rotary combine technology and tooling to Massey who, in turn sold out to linamar Corporation and Vicon Machinery, Inc. who, in turn, sold out to AGCO!
