This listing is for a rare, museum-quality set of two large brass nameplates salvaged from a single turbine-generator unit of a historic hydroelectric power plant in New England. The matched pair is an incredible piece of industrial history, chronicling the partnership between two American manufacturing giants of the early 20th century.
Historical Significance:
* Confirmed Pairing: The specifications on the plates are a confirmed match:
* S. Morgan Smith Turbine: 941 HP at 128.6 R.P.M.
* General Electric Generator: 700 KW at 128.5 R.P.M. (The HP-to-KW conversion and identical R.P.M. confirm they were coupled to the same shaft.)
* Probable Origin: Research strongly suggests this unit was installed at the Ellsworth Hydroelectric Dam on the Union River in Ellsworth, Maine, built circa 1908. This makes the set a tangible link to Maine's early industrial and power generation history.
