This mount was invented by George Haig of Glasgow, and originally known as the Scotch or Haig mount. In North America it became known as the barn door mount. The original version had a straight drive arm which accumulated tracking error, which was corrected in later versions with various modifications. The original article appeared in Sky and Telescope, April 1975 according to Wikipedia, where there is a discussion of some of the variants.
