This is a typical General Electric "A" case watt hour meter enclosure, of which I have many contemporaneous examples. My immediate hunch was the case and mech did not start life together, however I'd like to ask for you to snap a pic of the back of the case, and another of the mech removed from case, viewing the back of the mech. The dial appearance suggests Seth Thomas but I'd like to see pics of it a bit more apart, to offer a better opinion.
If this was made up for some purpose, it would not come as a surprise. "A" case meters were (are) customarily presented to retiring utility employees usually mounted and connected to some sort of table lamp, examples of which pop up on ebay on a regular basis. I have seen other special purpose meters presented this way which have complications, including those which have timepieces. This unit may have been a example of some kind of momento, but without a better look it's hard to know.
