Constructed from heavy cast brass, this industrial plaque was built for durability in some of the harshest mining environments of the late 19th and early 20th centuries.\u003c\/p\u003e\n\u003cp\u003eThe plate is prominently marked:\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\"The Aldrich Quintuplex Pump\"\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003e\"Built By The Allentown Rolling Mills\"\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003e\"Allentown, PA U.S.A.\"\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003ewith additional size and pump designation markings still visible.\u003c\/p\u003e\n\u003cp\u003eQuintuplex pumps represented advanced pumping technology for their era, engineered to move water efficiently in deep mining operations where constant groundwater intrusion threatened productivity. Heavy-duty industrial plaques like this were mounted directly onto mining machinery and surviving examples tied to historic mining operations are increasingly scarce today.\u003c\/p\u003e\n\u003cp\u003eThis example reportedly originated from the historic Emma Mine in California — a former copper mine located in central W½ sec. 11, T4N, R13W, SBM, on the S slope of Parker Mountain, N of Soledad Canyon Road — adding an additional layer of Western mining provenance and collector appeal. The equipment was pulled from the mine in 1959. The aged brass surface displays outstanding natural patina, industrial wear, and authentic character developed over decades of use and preservation.\u003c\/p\u003e\n\u003cp\u003ePieces like this are highly sought after by:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMining memorabilia collectors\u003c\/li\u003e\n\u003cli\u003eIndustrial archaeology enthusiasts\u003c\/li\u003e\n\u003cli\u003eWestern Americana collectors\u003c\/li\u003e\n\u003cli\u003eAntique machinery collectors\u003c\/li\u003e\n\u003cli\u003eSteampunk and industrial décor enthusiasts\u003c\/li\u003e\n\u003cli\u003eMuseum and historical display collections\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe bold raised lettering and substantial brass construction make this an outstanding display piece for offices, collections, workshops, or museum-style installations.\u003c\/p\u003e\n\u003cp\u003eMeasures: 9.75 x 5 inches, thickness is 4cm\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCondition:\u003c\/strong\u003e\u003cbr\u003ePlease review all photos carefully for overall condition, wear, patina, mounting holes, and historical surface character, as they are considered part of the description.
