Great pictures! The Ford is one of my favorite places anywhere.
They have some fabulous phonograph treasures but unfortunately almost all of them are in storage. On one of my research visits I found a cardboard beer flat on a storage shelf literally filled with spectacle carriage assemblies for the earliest Edison Class M.
If you had gone into Greenfield Village you would have seen several tinfoil phonographs in the Menlo complex, including an original Bergmann which they do operate for visitors and one of two suriving 'Brady' models (the other is at the Edison Site). There's also a phonograph 'store' adjacent to the Wright Brothers' bicycle shop but the machines and records in the window are a jumble covering a range of dates from early gold-moulded to Amberols. It's evocative, but not accurate.
