The Hamilton is interesting, it does not look like one. No top pilot ignition door, no perforated drum. But, the door looks Hamilton, rectagular window. And it appears that there may be a bottom lint trap. If the lint trap is at the bottom of the machine, it's a Hamilton. BTW, the Hamilton I found last fall found a home in Cleveland, was fixed and has gotten rave reviews from a very exacting collector. You don't see one very often, but they are treasures. matt
