I'm looking for information on the early Edison Homes. In Tim's "Compendium" on page 56 he shows a machine owned by Bill Koker that is serial number 394. It has the rectangular hole in the top casting. I have serial number 884 that is identical in all respects except for the rectangular hole. It appears the early machines had a unique half nut arm, fingers to hold the reproducer carraige at rest, a brass mandrel, a rectangular hole in the casting, and I'm not sure if there were motor differences. The write up in the Compendium indicates that the "fingers and hole" were soon abandoned. Based on my machine, it is apparent that the features did not disapper together. Do any of you have any information, by serial number, on when the different features were initiated and when they disappered. I'm also curious when the "C" reproducer holder on the carriage was discontinued.
